摘要： An SRAM cell having a latch circuit including two inverters coupled in a chain format. Each inverter is coupled to power through a transistor, and the transistor is turned off when data is written to the SRAM. As a result, the data is easily written to the SRAM cell without data collision since performance of the latch circuit is degraded. Such SRAM cell may be used in a flat panel display to temporarily store digital signals corresponding to data signals for displaying video.
