ABSTRACT:
The present invention discloses a digital-to-analog converter (DAC) with noise equalized and a device capable of equalizing noise in SRAM. In the DAC, when the BLANK signal is high, a transient current still flows to ground for equalizing noise. The device capable of equalizing noise in SRAM comprises a dummy read/write memory cell for adding read/write operations and a auto-detection circuit for detecting when to add read/write operations.
