System-on-chip including deepstop mode to reduce total leakage current and method thereof

摘要

A system-on-chip may include a hard-macro block, a deepstop control logic circuit, and/or a multi-threshold complementary metal-oxide-semiconductor (MTCMOS) logic circuit. The deepstop control logic circuit may be configured to transfer data to the hard-macro block from the multi-threshold complementary metal-oxide-semiconductor (MTCMOS) logic circuit during a normal mode. The deepstop control logic circuit may be configured to latch the data output from the MTCMOS logic circuit upon an entry into a deepstop mode and interrupt a power supply to the hard-macro block during the deepstop mode.
