Abstract
An improved memory for graphics displays includes an improved memory cell. Data may be written and read from the single bit cell simultaneously, eliminating the need for additional memory circuits to service an N column driver for a display. Additionally, the architecture of the memory allows for a signal input port for writing the data to the cell while allowing for multiple parallel output ports for reading the data. The unique architecture eliminates the need for addressing logic and refresh circuitry for display applications.
