Abstract
A method and apparatus allows single port memory devices to be accessed as pseudo two port memory devices. An access table is created to map the single port memory device to a single port even bank and a single port odd bank. The single port memory device is then accessed based on the mapping. An initial number of entries from the access table are retrieved in order to read addresses in the memory device until a predetermined delay expires. Simultaneous operations are then performed to read from rows in the memory device and write to rows in the memory device. Once all memory addresses have been read, write operations are sequentially performed in rows of the memory device based on the remaining entries of the access table.
