Abstract:
Methods, systems, and devices for differential amplifier schemes for sensing memory cells are described. In one example, a memory apparatus may include a differential amplifier having a first input node configured to be coupled with a memory cell and having an output node configured to be coupled with a sense component. In some examples, the memory apparatus may also include a capacitor having a first node coupled with the first input node, and a first switching component configured to selectively couple a second node of the capacitor with the output node. The differential amplifier may configured such that a current at the output node is proportional to a difference between a voltage at the first input node of the differential amplifier and a voltage at the second input node of the differential amplifier.
