Abstract
A multi-port memory cell () can be formed from seven transistors. Single ended write operations can be performed without a boosted word line voltage or variable power supply. A data value (D/DB) stored in the memory cell () can be cleared by shorting complementary data nodes (-and-) together. Write data can then be placed on a bit line. Complementary data nodes (-and-) can then be isolated once again, resulting in the write data being latched within the memory cell (). An access method () for a multi-port memory cell is also described.
