Current-holding circuit for memory cells, has inverting amplifier that generates sensor signal representing current, received by first holding node from memory cell, in response to received reference voltage

摘要

The circuit has a sensor having first and second ports which also serve as first and second holding nodes. The first port is connected to a memory cell. The circuit also has an inverting amplifier which has inverting input to which first holding node is connected, reference input for receiving reference voltage, and output to which second holding node is connected. The inverting amplifier generates a sensor signal in response to received reference voltage, and outputs the sensor signal to second holding node. The sensor signal represents current received by first holding node from memory cell. Independent claims are included for the following: (1) Current holding method; and (2) Computer program product storing the computer program of the current holding process.
