Abstract: A nonvolatile memory module includes a plurality of volatile memory devices sharing a data bus through which data is transmitted and a control bus through which a command and an address are transmitted; at least one nonvolatile memory device; and a controller including a backup logic which backs up data stored in the plurality of volatile memory devices when a fail in power of the host is detected or a backup operation is instructed from the memory controller of the host, wherein the backup logic sets a command address latency (CAL) of one among the plurality of volatile memory devices to a first value, and sets a command address latency of remaining volatile memory devices to a second value different from the first value.

Abstract: A nonvolatile memory module includes volatile memory devices; a nonvolatile memory device; and a controller suitable for backing up data stored in the volatile memory devices or restoring data backed up in the nonvolatile memory device, according to a fail/recovery of power of the host, the controller including a power-down interrupt logic which interrupts a backup operation when the power of the host is recovered while performing the backup operation, the power-down interrupt logic including: a logic which determines whether sufficient erased blocks exist in the nonvolatile memory device; a logic which erases a new block when the sufficient erased bocks do not exist; and an interrupt backup logic which backs up a volatile memory device having data corresponding to the erased block, when a fail in the power of the host is detected or a backup operation is instructed from the host.

Abstract: A nonvolatile memory module includes volatile memory devices sharing a data bus and a control bus; at least one nonvolatile memory device; and a controller for backing up data stored in the volatile memory devices into the nonvolatile memory device at a power failure of a host, and restoring data backed up in the nonvolatile memory device to the volatile memory devices at recovery of the power failure, the controller including: a command/address snooping logic for snooping on a command and an address inputted from a memory controller of the host, and analyzing amounts of stored data in the respective volatile memory devices; and a command/address control logic for selecting one of the volatile memory devices in order of the amounts of stored data based on analysis results of the command/address snooping logic, and backing up data of the selected volatile memory device in the nonvolatile memory device.
