SEMICONDUCTOR STORAGE DEVICE, SYSTEM, AND METHOD

摘要

A semiconductor storage system includes: a difference determining circuit configured to determine a difference between the number of first state values of sample data written to a memory and the number of first state values of read data read from the memory; and a compensation value determining circuit configured to determine a read voltage level compensation value corresponding to a difference between the number of the first state values of the sample data written to the memory and the number of the first state values of the read data read from the memory.
