Abstract
The present invention relates to an integrated circuit (IC) for SRAM (Static Random Access Memory) standby power reduction in LCD (Liquid Crystal Display) driver. The IC layout mainly disposes a high-current endurable transistor between a power supply pad and a power supply metal layer of the SRAM matrix. When the IC enters a standby mode, the electrical interconnection between the power supply pad and the power supply metal layer of the SRAM is cut off through the transistor so that the leakage current and the power consumption of the SRAM can be reduced.
