Abstract
A memory device includes: a memory cell capable of holding data; and an ECC circuit capable of generating a correction code and detecting an error based on the correction code. The memory cell is accessed by a pipeline operation. The pipeline operation includes at least four pipeline stages including a read cycle reading data from the memory cell, an ECC cycle executing generation of the correction code or error detection for the memory cell in the ECC circuit, a wait cycle during which processing for data related to the memory cell is not executed, and a write cycle writing data into the memory cell.
