Synchronous semiconductor integrated circuit capable of improving immunity from malfunctions |
摘要 |
A semiconductor memory device converts an automatic precharge signal, which is an asynchronous control signal, to a synchronous signal and inhibits a synchronous control circuit from an operation with respect to an illegal command in response to the converted signal. An internal malfunction with respect to the illegal command can be prevented due to this structure.
