SYNCHRONOUS READING NONVOLATILE MEMORY

摘要

PROBLEM TO BE SOLVED: To provide a nonvolatile memory which can perform synchronous reading with a frequency higher than a frequency which can be used now for data stored in a nonvolatile memory and which is operated by a burst reading mode. SOLUTION: This nonvolatile memory (10) is provided with an input pin (2) receiving an external clock signal supplied by a user, an input buffer (4) receiving the external clock signal and supplying an intermediate clock signal relating to the external clock signal and being delayed, and a delayed lock loop (12) receiving the intermediate clock signal and supplying the intermediate clock signal distributed in the nonvolatile memory and synchronizing with the external clock signal substantially.
