Abstract

PURPOSE:To reduce the access time in the static memory circuit, by detecting the change in the address signal and making equipotential the output of the digit line, data bus line and sense amplifier. CONSTITUTION:The control signal EQ is formed by catching the change in the access signal to produce the one shot signal. This control signal is fed to the gate of the equipotential transistor TRQ11, Q21 of digit line, data bus equipotential TRQ31, and sense amplifier equipotential TR41. Further, after the respective node is made for equipotential, the word line is toward the potential to select the potential of the memory cell. Thus, at the selection of memory cell, since the output of the digit line, data bus line and sense amplifier are respectively at the equipotential already, the time for the same potential can be omitted to quicken the access time.
