Abstract
A method for caching memory requests while accounting for a phase change memory cell drift phenomenon is described. The method includes writing first user data to an address in phase change memory cells; setting a timer in a set of data structures to a first value in response to writing the first user data to the phase change memory cells, wherein the data structures are stored outside the phase change memory cells; determining whether the timer corresponding to the first user data has expired; and fulfilling a read request for the address from the set of data structures in response to determining that the timer has not expired.
