Abstract

PURPOSE:To reduce power consumption by using a synchronizing clock, and generating a precharging clock and a sensing clock by a synchronous type static RAM. CONSTITUTION:When ka synchronizing clock rises from a level 0 to a level 1, a signal 0 is inputted to a precharging clock input 19 for a precharging period. A transfer gate 21 turns off and a memory cell 22 is unselected. Therefore, a precharging transistor 18 turns on and bit lines 20 and 20' are precharged to the level 1. When the signals of memory cells 6 and 22 from bit lines 4 and 4', and 20 and 20' are amplified, the width of the synchronizing clock is necessary invariably, so a new sensing clock is generated by using the synchronizing clock.
