PHASE CHANGE MEMORY CYCLE TIMER AND METHOD

摘要

A phase change memory (PCM) cycle timer and associated method are disclosed. A system includes at least one reference phase change element (PCE). The system also includes a circuit that performs a write operation on the at least one reference PCE and substantially immediately thereafter continuously senses and returns a value of a resistance of the at least one reference PCE throughout a settling time of the at least one reference PCE.
