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.
