Apparatus of calculating a power consumption in phase change memory phase change memory system including the apparatus and method of calculating power consumption in the phase change memory

摘要

An apparatus for calculating the power consumption amount of a phase change memory (PCM) includes a plurality of pipelines arranged to correspond to a plurality of sections with different power consumption amounts in a write command execution section so that data is transmitted according to time elapse, and an operation logic for calculating a total power consumption amount by summing power consumption change amounts at the time of data transmission between the pipelines. Accordingly, the present invention can reduce an area and shorten a calculation time.
