摘要： In an exemplary hidden refresh method for a pseudo SRAM, a system clock is received. A duty-on period of the system clock signal is adapted for performing a data access operation such as write or read operation. A refresh clock signal subjected to the control of the system clock signal is generated. A duty-on period of the refresh clock signal is non-overlapped with the duty-on period of the system clock signal. A refresh control pulse then is triggered by a starting edge of the duty-on period of the refresh clock signal to activate a word line, for performing a refresh operation.
