Abstract:
Methods, systems, and devices for a source follower-based sensing architecture and sensing scheme are described. In one example, a memory device may include a sense circuit that includes two source followers that are coupled to each other and to a sense amplifier. A method of operating the memory device may include transferring a digit line voltage to one of the source followers and transferring a reference voltage to the other source follower. After transferring the digit line voltage and the reference voltage, the source followers may be enabled so that signals representative of the digit line voltage and the reference voltage are transferred from the outputs of the source followers to the sense amplifier for sensing.
