ABSTRACT:
A sense amplifier having a conventional three transistor network for charging a column to a first predetermined voltage uses a depletion transistor to charge the column beyond the first predetermined voltage for detection of a memory cell which is in a non-conducting state. A memory cell in a conducting state draws enough current to prevent the depletion transistor from charging the column beyond the first predetermined voltage. A logic "1" is detected when the column charges beyond the first predetermined voltage to at least a second predetermined voltage, whereas a logic "0" is detected when the column does not reach the second predetermined voltage.
