    Abstract: Memories are provided. A memory includes a first memory array, a second memory array, and a read circuit. The first memory array is configured to store main data. The second memory array is configured to store complement data that is complementary to the main data. The read circuit includes a first sense amplifier, a second sense amplifier and an output buffer. The first sense amplifier is configured to provide a first sensing signal according to a reference signal and first data of the main data corresponding to a first address signal. The second sense amplifier is configured to provide a second sensing signal according to the reference signal and second data of the complement data corresponding to the first address signal. The output buffer is configured to provide one of the first sensing signal and the second sensing signal as an output according to a control signal.

    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.
