Patent ID: 7068563

Claim:
A method for accessing a multi-port memory having a common memory interface and a plurality of memory ports, the method comprising: decoding first address signals for accessing memory cells of a first memory array of the multi-port memory; coupling data between the first memory cell array and a first one of the plurality of memory ports in response to accessing memory cells of the first memory cell array through the first one of the plurality of memory ports; decoding second address signals for accessing memory cells of a second memory array of the multi-port memory; coupling data between the second memory cell array and a second one of the plurality of memory ports in response to accessing memory cells of the second memory cell array through the second one of the plurality of memory ports; decoding third address signals for accessing memory cells of the first or second memory cell array, the number of third address signals decoded for accessing memory cells of the first memory cell array the same as for accessing memory cells of the second memory cell array through the common memory interface; and coupling data between memory cells of the first or second memory cells array and the common memory interface in response to accessing memory cells of the first or second memory cell array through the common memory interface.
