Storage control device, storage device, information processing system, and storage control method

摘要

Provided is a storage control device including: a detection unit which detects a first timing for performing a first rewriting process of performing only a first operation from among the first operation and a second operation, in a memory cell array in which each bit transitions to a first storage state by the first operation and transitions to a second storage state by the second operation; and a request unit which makes a request for the first rewriting process with respect to the memory cell array, when the first timing is detected.

1. A storage control device comprising:
a detection unit which detects a first timing for performing a first rewriting process of performing only a first operation from among the first operation and a second operation, in a memory cell array in which each memory cell is configured to be transitioned to a first storage state by the first operation and to be transitioned to a second storage state by the second operation; and a request unit which makes a request for the first rewriting process with respect to the memory cell array, when the first timing is detected, wherein the first timing is when a number of errors in degraded first storage state or degraded second storage state is larger than a predetermined number.
