Single ended simpler dual port memory cell

摘要

A single ended simplex dual port memory cell is described. One port of the memory cell is dedicated for writing operations and the other port of the memory cell is dedicated for reading operations. A bit of data received from the first port can be stored in the memory cell. The second port can detect the memory cell contents substantially simultaneously as the memory cell is storing a bit of data from the first port. Each port is optimized for its respective dedicated operation. In other words, one port is optimized for write operations and the other port is optimized for read operations. Because one port of the memory cell is optimized for write operations and the other port of the memory cell is optimized for read operations, the cell does not require multiple wordline voltages for each port.
