A method of operating a computing system which includes a plurality of storage devices, a memory device, and a switch, is provided. The method includes: providing a first mapping request including first metadata corresponding to first user data to the memory device through the switch, by a first storage device of the plurality of storage devices; identifying a first standard corresponding to the first metadata based on the first mapping request, by the memory device; and generating first map data indicating a relationship between a first physical block address and a first logical block address of the first user data based on the first standard, by the memory device.

Computing system generating map data, and method of operating the same

A memory device is provided. The memory device includes: a buffer memory; a nonvolatile backup memory; and a memory controller configured to: store map data corresponding to an external storage device in the buffer memory; provide, in response to a request from the external storage device, an address pair corresponding to the request, from among address pairs of the map data, to the external storage device; and back up, in response to a sudden power-off event, the map data to the nonvolatile backup memory.

Memory device, storage device, and computing system including memory device and storage device

One embodiment of a method includes loading, by a memory controller, a boot image from a solid state drive to an operating memory of a computing system during an initialization operation of the computing system. The initialization operation initializes components of the computing system.

Method of managing a solid state drive, associated systems and implementations

Memory modules and authorization systems include a nonvolatile memory, an authentication engine configured to receive an initialization request from a user system, configured to generate a certification value based on device identifiers of devices includes in the user system in response to the initialization request and configured to control access to the nonvolatile memory based on the certification value, and a certification value storage configured to store the certification value.

Nonvolatile memory modules and authorization systems and operating methods thereof

A data storage device includes a non-volatile memory device including a memory cell array, where the memory cell array includes a first region and a second region, and a memory controller configured to judge whether a size of data externally provided according to a write request exceeds a reference size, and to control the non-volatile memory device according to a judgment result. When the externally provided data exceeds the reference size, the memory controller controls the non-volatile memory device such that a portion of the externally provided data is stored in the second region via a main program operation and such that a remainder of the externally provided data is stored in the first region via a buffer program operation.

System including data storage device, and data storage device including first and second memory regions

A nonvolatile memory is provided which includes a memory cell array including a plurality of nonvolatile memory cells; a decoder connected with the memory cell array through a plurality of word lines; a data input/output circuit connected with the memory cell array through a plurality of bit lines; a voltage detector configured to detect a variation in a power supply voltage to output a voltage variation signal; and control logic configured to control the decoder and the data input/output circuit such that data stored at the memory cell array is invalidated in response to the voltage variation signal.

Data storage device, controller, and operating method of data storage device

A solid state drive may include one or more memory cell arrays divided into a plurality of blocks. A first portion of the blocks may be designated for storing user data and a second portion of the blocks may be designated as reserved blocks for replacing defective blocks in the first portion. In one embodiment, the method includes reformatting, by a memory controller, the solid state drive to convert one or more blocks in the first portion into reserved blocks.
