INTEGRATED CIRCUIT STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a memory architecture for reducing variation of a data-retention power supply voltage. SOLUTION: This integrated circuit structure includes an active power supply line and a data-retention power supply line. A memory macro is connected to the active power supply line and the data-retention power supply line. The memory macro includes a memory cell array and a switch. The switch is configured to switch a connection between connecting the memory cell array to the active power supply line and connecting the memory cell array to the data-retention power supply line. The data-retention power supply line is outside of the memory macro. COPYRIGHT: (C)2011,JPO&INPIT
