Title: Semiconductor storage device
Inventor: YOSHIDA MASANOBU
IPC: G11C16/06
Filed: 1982-06-30
Abstract: PURPOSE:To read data at a high speed by clamping a bit line potential automatically and selectively only when it drops to a negative potential during discrimination on read data which is made according to whether a current leaking from a sensor amplifier to a bit line is present or not. CONSTITUTION:A level clamping circuit, e.g. level clamping gate 41 is added to a circuit with an EPROM. The gate 41 is grounded through an MIS transistor with a threshold voltage OV. When the source potential on the bit line side to the gate is to drop negatively, the gate turns on to inhibit transistion to a negative potential by a positive potential supplied from the drain, and raises it to the voltage OV or a positive voltage. Consequently, the bit line potential is read at a high speed without being negative in any case.
