METHOD OF MANAGEMENT OF REAL-TIME ACCESS TO A DIFFERENCE MEMORY, DIFFERENCE MEMORY AND ELECTRONIC SYSTEM INCLUDING DIFFERENCE MEMORY

摘要

A management method of real-time access to logic data stored in a differential memory (1), in particular a phase-change memory, operated in single-ended mode and comprising a first main memory module (4a), which stores first logic data to be refreshed, and an auxiliary memory module (6). The method comprises the steps of: storing (24) second logic data in the auxiliary memory module, copying the first logic data; refreshing (28) the first logic data; and fetching (26, 30), in response to a request for reading the first logic data, the second logic data during the step of refreshing (28) of the first logic data, and fetching the first logic data, otherwise.
