Semiconductor memory system including a plurality of semiconductor memory devices

摘要

A communication line is connected to first and second chips, and held at a first signal level. A monitor circuit changes a signal level of the communication line from the first signal to a second signal level while one of the first and second chips uses a current larger than a reference current. When the signal level of the communication line is the second signal level, the other of the first and second chips is controlled to a wait state that does not transfer to an operating state of using a current larger than the reference current.

1. A semiconductor memory system comprising:
a first semiconductor memory device; a second semiconductor memory device; and a controller electrically connected to the first and second semiconductor memory devices, wherein when one of the first and second semiconductor memory devices consumes a current larger than a reference current, the controller controls the other of the first and second semiconductor memory devices to a waiting state.
