Abstract
A memory system includes a host interface, a nonvolatile memory, a power supply circuit, a protection circuit, and a first voltage monitor circuit. The power supply circuit is between the host interface and the nonvolatile memory, and supplies primary power to the nonvolatile memory. The protection circuit is between the host interface and the power supply circuit, and configured to clamp a power supply signal supplied from the host interface to the power supply circuit to a first voltage. The first voltage monitor circuit is between the host interface and the protection circuit, and configured to monitor a voltage level of the power supply signal supplied from the host interface and cause the voltage level of the power supply signal supplied to the power supply circuit to be decreased from the first voltage to a second voltage when the monitored voltage level is below a first threshold voltage.
