Continuous page read for memory
View Patent ↗Subject matter disclosed herein relates to techniques to read memory in a continuous fashion.
1. A method comprising:
reading a first page of data and providing said first page of data to be stored in a page buffer in response to receiving a first portion of a memory address of said first page;
fetching words of said first page of data stored in said page buffer in response to receiving an additional portion of said memory address of said first page;
monitoring a count of said words fetched from said page buffer; and
in response to said count reaching a particular threshold number less than a number of said words of said first page of data, sensing a second page of data before completing, and while continuing, said fetching words of said first page.
2. The method of claim 1 , further comprising:
providing said second page of data to said page buffer in response to a last word of said first page of data being fetched.
3. The method of claim 1 , wherein initiating said sensing of said second page of data is performed automatically without receiving an address for said second page of data.
4. The method of claim 1 , wherein said first portion of said memory address comprises an address of said first page of data and said additional portion of said memory address comprises least significant bits of said memory address to identify said words of said first page of data.
5. A method comprising:
reading a first page of data and providing said first page of data to be stored in a page buffer in response to receiving a first portion of a memory address of said first page;
fetching words of said first page of data stored in said page buffer in response to receiving an additional portion of said memory address of said first page;
sensing a second page of data before completing said fetching words of said first page; and
toggling said additional portion of said memory address between two values, wherein said fetching said words of said first page of data is performed synchronously with said toggling, and wherein said additional portion of said memory address comprises a single bit of said memory address.
6. The method of claim 1 , wherein said fetching words of said first page is performed synchronously with changing a value of said additional portion of said memory address.
7. The method of claim 1 , wherein said first portion of said memory address corresponds to two or more pages.
8. A memory device comprising:
a controller to:
read a page of data and provide said page of data to be stored in a page buffer in response to receiving a first portion of a memory address of the page of data;
fetch words of said page of data stored in said page buffer in response to receiving an additional portion of said memory address;
monitor a count of said words fetched from said page buffer; and
in response to said count reaching a particular threshold number less than a number of said words of said page of data, read a subsequent page of data before completing, and while continuing, said fetching words of said page of data.
9. The memory device of claim 8 , wherein said controller is adapted to flush said subsequent page of data into said page buffer in response to a last word of said page of data being fetched.
10. The memory device of claim 8 , wherein said controller is configured to initiate said sense of said subsequent page of data automatically without receiving an address for said subsequent page of data.
11. The memory device of claim 8 , wherein said first portion of said memory address comprises an address of said page of data and said additional portion of said memory address comprises least significant bits of said memory address to identify said words of said page of data.
12. A memory device comprising:
a controller to:
read a page of data and provide said page of data to be stored in a page buffer in response to receiving a first portion of a memory address of the page of data;
fetch words of said page of data stored in said page buffer in response to receiving an additional portion of said memory address;
sense a subsequent page of data before completing said fetching words of said page of data; and
toggle said additional portion of said memory address between two values, wherein said fetching said words of said page of data is performed synchronously with said toggling, and wherein said additional portion of said memory address comprises a single bit of said memory address.
13. The memory device of claim 8 , wherein said fetching words of said page is performed synchronously with changing a value of said additional portion of said memory address.
14. The memory device of claim 8 , wherein said first portion of said memory address corresponds to two or more pages.
15. A system comprising:
a memory device comprising an array of memory cells, said memory device further comprising a controller to:
read a page of data and flush said page of data to be stored in a page buffer in response to receiving a first portion of a memory address of said page of data;
fetch words of said page of data stored in said page buffer in response to receiving an additional portion of said memory address;
monitor a count of said words fetched from said page buffer; and
in response to said count reaching a particular threshold number less than a number of said words of said page of data, read a subsequent page of data before completing, and while continuing., said fetching words of said first page; and
a processor to host one or more applications and to initiate a write command to said controller to provide access to said memory cells.
16. The system of claim 15 , wherein said controller is configured to initiate said sense of said subsequent page of data automatically without receiving an address for said subsequent page of data.
17. The system of claim 15 , wherein said first portion of said memory address comprises an address of said page of data and said additional portion of said memory address comprises least significant bits of said memory address to identify said words of said page of data.
18. The method of claim 5 , wherein initiating said sensing of said second page of data is performed automatically without receiving an address for said second page of data.
19. The method of claim 5 , further comprising providing said second page of data to said page buffer in response to a last word of said first page of data being fetched.
20. The memory device of claim 12 , wherein said controller is configured to initiate said sense of said subsequent page of data automatically without receiving an address for said subsequent page of data.
21. The memory device of claim 12 , wherein said controller is configured to flush said subsequent page of data into said page buffer in response to a last word of said page of data being fetched.
22. A system comprising:
a memory device comprising an array of memory cells, said memory device further comprising a controller to:
read a page of data and flush said page of data to be stored in a page buffer in response to receiving a first portion of a memory address of said page of data;
fetch words of said page of data stored in said page buffer in response to receiving an additional portion of said memory address;
sense a subsequent page of data before completing said fetching words of said first page; and
toggle said additional portion of said memory address between two values, wherein said fetching said words of said page of data is performed synchronously with said toggling, and wherein said additional portion of said memory address comprises a single bit of said memory address; and
a processor to host one or more applications and to initiate a write command to said controller to provide access to said memory cells.
23. The system of claim 22 , wherein said controller is configured to initiate said sense of said subsequent page of data automatically without receiving an address for said subsequent page of data.
24. The system of claim 22 , wherein said controller is configured to flush said subsequent page of data into said page buffer in response to a last word of said page of data being fetched.
