Semiconductor memory device rewriting data after execution of multiple read operations |
摘要 |
Provided is a semiconductor memory device including a memory cell; a writing driver providing a program current to the memory cell to write data in the memory cell; a sense amplifier processing a read operation reading data written in the memory cell; and a controller providing a rewriting signal for rewriting data read from the sense amplifier in the memory cell to the writing driver after the sense amplifier repeatedly applies a read operation more than a predetermined number of times.
