Abstract: An embedded auto-refresh circuit is provided to automatically refresh pseudo static random access memory cells. The embedded auto-refresh circuit includes a shift register and an auto-refresh generation circuit. The shift register is driven by a clock signal to perform shift operations. The auto-refresh generation circuit has a pre-charge and refresh signal generator driven by the clock signal to generate a refresh signal and a pre-charge signal. The pre-charge signal has a first pulse and a second pulse. In a memory access cycle, a plurality of memory cells on a word line determined by the refresh signal and the shift register are refreshed by a pseudo read operation based on the first pulse and the refresh signal, and then a general random memory access process is performed by taking the second pulse as a pre-charge signal.
