Four device SRAM cell with single bitline

摘要

A memory cell includes a static inverter having an input connected to a storage node. An impedance connects the storage node to a voltage supply. A first transistor, having an input connected to an output of the static inverter, connects the storage node to a write line. Lastly, a second transistor, responsive to a wordline access signal, connects the storage node to a single data bitline. The memory cell further includes a single ended four transistor CMOS SRAM cell. Additionally, a memory array is disclosed which includes a plurality of memory cells arranged to form a matrix of rows and columns, each memory cell including a single ended four transistor CMOS SRAM cell.
