SEMICONDUCTOR MEMORY DEVICE HAVING PROCESSOR RESET FUNCTION AND RESET CONTROL METHOD THEREOF

摘要

A semiconductor memory device for use in a multiprocessor system includes a shared memory area and a reset signal generator. The shared memory area is accessible by the processors of the multiprocessor system through different ports, and is assigned to a portion of a memory cell array. The reset signal generator is configured to provide a reset enable signal to a processor, predetermined as a slave processor among the multiple processors, for a predetermined time after an initial booting of the multiprocessor system. The reset signal generator also provides a reset disable signal to the slave processor after the predetermined time lapses.
