STORAGE CONTROL DEVICE, STORAGE DEVICE, AND INFORMATION PROCESSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/095522
Kind Code:
A1
Abstract:
The state of reference cells in a storage device is correctly managed. A first memory cell array includes a first reference cell that generates the reference potential of a sense amplifier. A second memory cell array includes a second reference cell that generates the reference potential of the sense amplifier. A state storage unit stores a state indicating the probability of a held value for each of the first and second reference cells. When a read is instructed on either the first or second reference cell, a read control unit controls the indicated read on the basis of the states relating to the first and second reference cells stored in the state storage unit.
