Title: Adjusting circuit for bit line sense amplifier
Inventor: KIM JEONG HWAN
IPC: G11C11/34
Filed: 1998-12-31
Abstract: PURPOSE: An adjusting circuit for a bit line sense amplifier is provided to adjust a time section that supplies outer voltage for rapid increase of a driving signal without a timing control circuit and a transformer. CONSTITUTION: Two electric potential comparators are activated by a SAEN as an enable signal of a sense amplifier and a PX as a low coding signal. Two latch outputs(SP1)(SP2) are transited in a low status. A ninth and a tenth PMOS transistors supply outer voltage to a pre charged SPC. A first comparator intercepts the supply of outer voltage to the SPC at the beginning of increasing SPC electric potential. However, a second comparator having a relatively high reference voltage keeps in a low status of SP2 to supply electric charge to the SPC so that wanted level of voltage keeps going. The SNC signal output is controlled by an SN1 and an SN2 signal inputted from an outside.
