Abstract

PURPOSE:To speed up the readout and write-in cycle, by obtaining the readout information from the preamplifier of MISFET. CONSTITUTION:Between the drive MISFETs Q1, Q2 in which each drain is connected to another gate and the sources are commonly connected, and data lines D, -D, the cut MISFETs Q3, Q4 are provided and between Q1, Q2 and the reference potential, the switching MISFET Q5 is provided. Q10, Q11 are respectively provided between Q1, Q2 and readout circuit 2 and Q8, Q9 are provided between Q1, Q2 and readout circuit 3. The preamplifier and input/output circuit are constituted by them. Readout is made from the preamplifier side of Q3, Q4 and write-in information is fed to the data line of Q3, Q4.
