Method and apparatus for address allotting and verification in a semiconductor device
View Patent ↗A semiconductor device includes a CAM cell array that stores the operation setting information as to the semiconductor device, a controller that controls read and write of the CAM cell array, a row decoder, and a column decoder. With this structure, different row addresses are allocated to respective functions of the operation setting information. Accordingly, stress is not caused in the CAM cell array of the unselected functions at the time of programming.
1. A method of allocating addresses to a cell array that stores operation setting information for a semiconductor device, the method comprising the step of:
allocating different row addresses to respective functions of the operation setting information wherein the operation setting information is allocated to column addresses selected by one of the row addresses.
2. The method as claimed in claim 1 , further comprising the step of:
allocating different column addresses for the respective functions of the operation setting information.
3. The method as claimed in claim 1 , further comprising the step of:
allocating continuous column addresses for the respective functions of the operation setting information.
4. The method as claimed in claim 3 , further comprising the step of:
selecting all word lines on the cell array and successively changing the column addresses to read data from the cell array.
5. A method of allocating addresses, comprising:
providing a memory cell array that stores operation setting information for a semiconductor device; and
allocating different row addresses to respective functions of the operation setting information wherein the operation setting information is allocated to column addresses selected by one of the row addresses.
6. The method as claimed in claim 5 , further comprising the step of:
allocating different column addresses for the respective functions of the operation setting information.
7. The method as claimed in claim 5 , further comprising the step of:
allocating continuous column addresses for the respective functions of the operation setting information.
8. The method as claimed in claim 7 , further comprising the step of:
selecting all word lines on the cell array and successively changing the column addresses to read data from the cell array.
9. A method of allocating addresses to a cell array that stores operation setting information for a semiconductor device, the method comprising the step of:
allocating different row addresses to respective functions of the operation setting information;
allocating operation setting information to column addresses selected by one of the row addresses; and
reading out data with column addresses for respective functions of the operation setting information.
10. The method as claimed in claim 9 , further comprising the step of:
allocating different column addresses for the respective functions of the operation setting information.
11. The method as claimed in claim 9 , further comprising the step of:
allocating continuous column addresses for the respective functions of the operation setting information.
12. The method as claimed in claim 11 , further comprising the step of:
selecting all word lines on the cell array and successively changing the column addresses to read data from the cell array.
