Abstract

PURPOSE:To make read-out of cells higher in speed by applying the predetermined comparing potential obtained in a comparing potential generating circuit for information writing and reading. CONSTITUTION:The OR signal S3 of an OR signal S2 and an output data sgnal S0 is obtained with the collector of a transistor Q8, and the OR signal S3' of the signal S2 and the NOT signal of the S0 with the collector of Q8'. The AND signal S4 of the signal S3 and the OR signal S1 obtainable from the collector of Q1 is obtained in the base of Q4, and the AND signal S4' of the signal S3' and the S1' in the base of Q4'. A comparing potential VC is obtained from the mid-point of the connection of a resistance R2 and a current source I2, and a comparing potential VC' from the mid-point of the connection of R2' and I2'. The respective comparing potentials control the operation of bipolar transistors for information writing and reading.
