Abstract
A storage device provides single-port read multiple-port write functionality and includes first and second memory arrays and a controller. The first memory array includes first and second single-port memory cells. The second single-port memory cell stores data in response to a memory access conflict associated with the first single-port memory cell. The second memory array stores location information associated with data stored in the first and second single-port memory cells. The controller is operatively coupled to the first and second memory arrays, and resolves the memory access conflict by determining locations to store data in the first and second single-port memory cells to thereby avoid a collision between concurrent memory accesses to the first single-port memory cell in response to the memory access conflict. The controller determines locations to store data in the first and second single-port memory cells based on the location information.
