Abstract
A zero-drift analog memory (ZDAM) cell that indefinitely maintains an output signal at a discrete voltage while the memory circuit is powered, wherein the memory circuit receives an input signal, passes the input signal to a storage element upon receiving an assertion signal, maintains an output signal at a level of the input signal when the assertion signal is removed, and utilizes a zero-drift transfer function feedback loop on the output signal to maintain the output signal. A memory array including a plurality of ZDAM cells and method of operation are also disclosed.
