A memory system includes multiple storage devices that each include a nonvolatile memory device. A client device is configured to collect deterioration information of the nonvolatile memory devices provided from the storage devices. A server device is configured to receive the collected deterioration information and to predict a degree of deterioration of the nonvolatile memory devices in real time by performing machine learning based on the collected deterioration information and initial deterioration information. The client device determines a read level of the nonvolatile memory device based on the degree of deterioration of the nonvolatile memory devices from the server device. The storage device sets the nonvolatile memory device to operate based on the read level determined in the client device.

Storage device, memory system, and read voltage decision method thereof

A storage device includes a nonvolatile memory device, a buffer memory, a controller and a neuromorphic chip. The neuromorphic chip is configured to generate an access classifier based on the access result information and the access environment information. The controller is configured to perform first accesses to the nonvolatile memory device using the buffer memory and to collects the access result information and the access environment information of the first accesses in the buffer memory. The controller is configured to perform a second access of the nonvolatile memory device using the buffer memory. The controller is configured to obtain a prediction result of access parameters associated with the second access by using access environment information associated with the second access and the access classifier.

Storage device including nonvolatile memory device and access method for nonvolatile memory device

A storage device may include a nonvolatile memory device, a buffer memory, and a controller. The controller may perform first accesses on the nonvolatile memory device using the buffer memory, collect access result information and access environment information of the first accesses in the buffer memory, and generate an access classifier that predicts a result of a second access to the nonvolatile memory device by performing machine learning based on the access result information and the access environment information collected in the buffer memory.

Storage devices including nonvolatile memory devices and access methods for nonvolatile memory devices

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

Disclosed is a data managing method of a storage device which includes at least one nonvolatile memory device and a controller controlling the nonvolatile memory device. The data managing method includes receiving an input/output request and generating a section directing logical addresses based on the input/output request. The section is managed using section information, and the section information includes a start logical address corresponding to the input/output request, spatial locality information having the number of the directed logical addresses, and historical request information.

Storage device and data management method thereof

A method of controlling a storage device, the method including calculating, in a controller of the storage device, data throughput of the storage device in a current period, comparing, in the controller, the data throughput to a reference value and adjusting, with the controller, an operation performance of the storage device in a next period based on the comparison and a delay factor of a period prior the current period.

Method for adjusting performance of a storage device and a semiconductor storage device therefor

Provided are a flash memory system and a driving method thereof. A flash memory device according to an embodiment of the present invention includes a memory cell array including a plurality of memory cells, and a control logic. The control logic performs control for one-bit information to be stored in the plurality of memory cells. The control logic controls storing data in the plurality of memory cells multiple times without an erasion operation. Accordingly, the flash memory device does not execute an erasion operation, increasing an operation speed.

Memory device and program method thereof

A storage apparatus includes a memory unit and a controller to set up a memory space of the memory unit as a user data space and a spare space according to a signal representing at least one of the user data space and spare space. An electronic apparatus controls the storage apparatus, and a method controls at least one of the storage apparatus and the electronic apparatus to control a memory space of the storage apparatus.

Defining and changing spare space and user space in a storage apparatus

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.
