Title: Dynamic semiconductor memory
Inventor: WATANABE YOJI
IPC: G11C11/409
Filed: 1988-03-15
Abstract: PURPOSE:To avoid deterioration in action margin by using an amplitude limiting circuit which limits the charge/discharge amplitude of a pair of bit lines to an equal level between high and low level side bit lines and at the same time to a level lower than 1/2 power supply voltage respectively in an active state. CONSTITUTION:The precharge value of a pair of bit lines BL and BL are set at 1/2VCC and the amplitude is limited to a level equal between the high and low level sides set by the charging and discharging of the pair of lines BL and BL in an active state. That is, 1/2VCC+DELTAV and 1/2VCC-DELTAV are set by an amplitude limiting circuit 21 (VCC: power supply voltage). Then the circuit 21 limits the amplitude to an equal level between the high and low level side bit lines. Thus it is possible to avoid the deterioration in the action margin.
