Title: Semiconductor memory
Inventor: TSUKIDE MASAKI
IPC: G11C5/14
Filed: 1995-01-12
Abstract: PURPOSE: To attain low voltage, high speed sense operation by reducing an absolute value of a threshold value voltage of a transistor forming a sense amplifier than the absolute value of the threshold value voltage of the time when the voltage between a back gate and a source is zero. CONSTITUTION: When the sense amplifier starts the sense operation, n channel back gate potential VBN imparted to a (p) well 303a forming (n) channel sense amplifier Trs 224c, 224d is made (n) channel precharge potential higher than bit line precharge potential VBL and lower than the potential adding pn connection diffusion potential between the well 303a and the sources/drains 224ca, 224cb, 224cd of the Trs 224c, 224d to the potential VBL. Thus, since the threshold value voltages of the Trs 224c, 224d when the sense operation is started become small, the low voltage, high speed sense operation is attained.  Further, since the potential VBN is made grounded potential VSS when the amplifier operation of the sense amplifier is ended, the threshold values of the Trs 224c, 224d become large compared with the time when the sense operation is started, and power consumption at the time of latching the data is reduced.
