ABSTRACT:
A memory cell comprising field effect transistors for use in a random access memory array. The cell is of the dynamic type wherein data is stored on capacitive elements, and is self-refreshing; no circuitry external to the array is needed for refresh, other than clock sources. Five MOS field effect transistors are employed, with two non-overlapping clocks, a data buss for each row of the array and one address line for each column. The transistors and associated capacitors are arranged to reinforce a stored "1" or "0".
