Title: Sense amplifying circuit of semiconductor memory
Inventor: TAGUCHI MASAO
IPC: G11C7/06
Filed: 1980-09-26
Abstract: PURPOSE:To obtain a sense amplifying circuit including a recharging circuit having high efficiency, by amplifying a sense output with a reverse amplifier to charge a bit line. CONSTITUTION:A minute potential difference which is caused to a bit line from a memory cell and a dummy cell is sensed via a transistor Q17 which is turned on according to a clock phis. WIth some delay to the clock phis, transistors Q20 and Q21 that form a reverse amplifier together with transistors Q18 and Q19 conduct. Then the bit line having a reduced sensing action is charged via a transistor Q22 or Q23 to increase the potential. As a result, the recharging is carried out with high efficiency without providing a circuit that raises up the bit line voltage to a high potential. Thus the access time can be shortened to realize an optimum sense amplifying circuit which performs the precharging with a low potential.
