Abstract
A method and system for testing a multi-port memory cell are described. According to one embodiment of the invention, a multi-port memory device comprises an array of multi-port memory cells. Accordingly, each multi-port memory cell is connected to one word-line and two bit-lines per read/write port. The memory device includes memory testing logic to perform a first memory access operation (e.g., read/write) at a first port of the multi-port memory cell while the memory cell is in a stressed condition. For example, the first memory access operation occurs while a second memory access operation is emulated on a second port. Moreover, the memory access operations occur at a frequency that is substantially equivalent to a maximum operating frequency of the dual-port memory device.
