  • Publication number: 20240097570
    Abstract: According to one embodiment, a memory system connectable to a host includes a nonvolatile memory, a controller, and a power control circuit. The controller controls the nonvolatile memory. The power control circuit controls power to be supplied to the controller and the nonvolatile memory and includes one or more DC/DC converters. The nonvolatile memory and the controller include one or more circuit blocks. Each of the one or more DC/DC converters supplies an internal power supply voltage to one of the one or more circuit blocks. A first DC/DC converter of the one or more DC/DC converters transitions to a forced pulse width modulation mode in response to the memory system that has transitioned from a low power consumption mode to a normal operation mode.
