MEMORY DEVICE WITH LOW POWER OPERATION MODE

摘要

A memory device that operates in a low-power operation mode includes a memory cell array, a page size changing circuit, and an encoding and decoding changing circuit. The page size changing circuit changes the number of data items prefetched in the memory cell array according to a power mode during a read operation. The encoding and decoding changing circuit changes a level of data written in the memory cell array according to the power mode during a read operation.
