Systems and methods for packing data in a scalable memory system protocol
A memory device includes a memory component that stores data and a processor. The processor may receive requests from a requesting component to perform a plurality of data operations, generate a plurality of packets associated with the plurality of data operations, and continuously transmit each of the plurality of packets until each of the plurality of packets are transmitted. Each of the plurality of packets after the first packet of the plurality of packets is transmitted on a subsequent clock cycle immediately after a previous packet is transmitted.
1. A method, comprising:
receiving a stream of bits that comprises a plurality of sets of data;
identifying a logic value of one bit in the stream of bits; and
determining a transaction type of a first set of data of the plurality of sets of data, wherein the first set of data follows the one bit, wherein the transaction type is determined based at least in part on one or more values of one or more bits in the first set of data.
2. The method of claim 1 , wherein the plurality of sets of data corresponds to a plurality of data packets.
3. The method of claim 1 , wherein at least two sets of data of the plurality of sets of data have different transaction types.
4. The method of claim 1 , wherein the stream of bits comprises a plurality of data packets, wherein one of the plurality of data packets comprises the first set of data and a second set of data.
5. The method of claim 4 , wherein the first set of data corresponds to a first transaction type and the second set of data corresponds to a second transaction type.
6. The method of claim 1 , further comprising:
determining a location of an error control code (ECC) bit or bits of the first set of data based at least in part on the transaction type.
7. The method of claim 6 , further comprising:
identifying or correcting an error in the first set of data based at least in part on the ECC bit or bits.
8. The method of claim 1 , further comprising:
determining an operation for the first set of data based at least in part on the transaction type, wherein the operation comprises a read operation, a transmission operation, a read-modify-write operation, a pattern write operation, a write-with-enable operation, a write operation, or any combination thereof.
9. The method of claim 1 , wherein the one or more values of the one or more bits in the first set of data corresponds to an index to a look-up table comprising a list of a plurality of transaction types.
10. An apparatus, comprising:
a plurality of memory types; and
an integrated circuit configured to:
receive a stream of bits that comprises a plurality of sets of data;
identify a logic value of one bit in the stream of bits; and
determine a transaction type of a first set of data of the plurality of sets of data, wherein the first set of data follows the one bit, wherein the transaction type is determined based at least in part on one or more values of one or more bits in the first set of data.
11. The apparatus of claim 10 , wherein the plurality of sets of data corresponds to a plurality of data packets.
12. The apparatus of claim 10 , wherein at least two sets of data of the plurality of sets of data have different transaction types.
13. The apparatus of claim 10 , wherein the first set of data corresponds to a first transaction type and a second set of data corresponds to a second transaction type.
14. The apparatus of claim 13 , wherein the first transaction type and the second transaction type are the same.
15. A system, comprising:
a plurality of memory types;
an integrated circuit configured to couple to the plurality of memory types via a plurality of busses, wherein the integrated circuit is configured to:
receive a stream of bits comprising a plurality of sets of data;
identify a logic value of one bit in the stream of bits; and
determine a transaction type of one set of data of the plurality of sets of data that follows the one bit, wherein the transaction type is determined based at least in part on information provided in the one set of data and a look-up table comprising a listing of a plurality of transaction types.
16. The system of claim 15 , wherein the integrated circuit is further configured to determine a location of an error control code (ECC) bit or bits of the one set of data based at least in part on the transaction type.
17. The system of claim 16 , wherein the integrated circuit is further configured to:
identify or correct an error in the one set of data based at least in part on the ECC bit or bits.
18. The system of claim 15 , wherein the integrated circuit is further configured to:
determine an operation for the one set of data based at least in part on the transaction type, wherein the operation comprises a read operation, a transmission operation, a read-modify-write operation, a pattern write operation, a write-with-enable operation, a write operation, or any combination thereof.
19. The system of claim 15 , wherein the integrated circuit is further configured to:
identify one of the plurality of transaction types in the listing based on the information and the listing of a plurality of transaction types via the look-up table.
20. The system of claim 15 , wherein the transaction type is indicative of a first size of a payload field and a second size of an error control code (ECC) field in the one set of data.
