Classification: CPC G  H | IPC G  H

Claim 8:
9. A memory system, comprising:
a non-volatile memory including a plurality of chips;
a controller for writing data to the non-volatile memory and reading data from the non-volatile memory; and
a power supply circuit including a capacitor, the power supply circuit configured to supply power to the non-volatile memory and the controller from an external power supply and from the capacitor when the external power supply is interrupted, wherein
the controller is configured to control the power supply circuit to track expected current consumption associated with execution of commands by the non-volatile memory and charge the capacitor during times when either the expected current consumption of the non-volatile memory is less than a first current level or the expected current consumption is greater than the first current level but the time since a previous charging of the capacitor exceeds a threshold length of time.
