Semiconductor memory for logic-hybrid memory

摘要

This invention provides ways to intercept abnormal power signals to prevent damaging the memory in a semiconductor. To achieve this, the semiconductor memory comprises a first control signal line controlling a selection from row addresses, a second control signal line controlling a selection from column addresses, a first voltage control means cutting off the first control signal line in case that predetermined number of control signals are abnormal, and a second voltage control means cutting off the second control signal line in case that predetermined number of control signals are abnormal.
