    Abstract: The present disclosure describes an adjustment circuit that can be used, for example, in a memory system with partitioned memory blocks. The adjustment circuit can include a controller circuit, a timer circuit, and a temperature adaptive reference (TAR) generator. The controller circuit can be configured to output a control signal that indicates a memory type (e.g., code memory or data memory) associated with a partitioned memory block. The timer circuit can be configured to output a timing signal for a read memory operation based on the control signal. And, the TAR generator can be configured to adjust a verify reference current for a verify memory operation based on temperature, where the verify reference current is set based on the control signal.

    Abstract: A device includes memory cells, a reference circuit, and a sensing unit. The reference circuit includes a first reference switch, a second reference switch, and reference storage units. The first reference switch is turned on when a reference word line is activated. The second reference switch is turned on when the reference word line is activated. The reference storage units include a first reference storage unit and a second reference storage unit. The first reference storage unit generates a first signal having a first logic state when the first reference switch is turned on. The second reference storage unit generates a second signal having a second logic state when the second reference switch is turned on. The sensing unit determines a logic state of the bit data of one of the memory cells according to the first signal and the second signal.
