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.
Claims4
A device capable of equalizing noise in SRAM memory, comprising:
- an auto-detection circuit, with an address signal of said SRAM coupled;
- and
- a dummy memory cell, performing corresponding read/write operations in response to the output of said auto-detection circuit.
Dependencies are inferred from the claim text.
