Nonvolatile memory, semiconductor device, and method of programming to nonvolatile memory |
摘要 |
Disclosed is a nonvolatile memory with a shortened total write time, capable of stably writing data by making a write current constant while reducing fluctuations in a voltage generated by a booster circuit. In a nonvolatile memory such as a flash memory, data is determined at the time of writing operation. While skipping a bit corresponding to write data having the logic "1" (or logic "0"), writing operation to bits corresponding to write data having the logic "0" (or logic "1) is successively performed.
