In an embodiment of the disclosed technology, a defective memory region is detected on the basis of operation information of a memory region included in a memory system and allocated to a host device, a warning signal is transmitted to a host device to which the defective memory region is allocated, and the defective memory region is excluded from a pool of allocatable memory regions to reduce or prevent data loss of a host device using memory regions of the memory system that may occur due to the defective memory region.

Data storage device, system and controller

An embodiment of the disclosed technology reduces direct data transmission and reception between a plurality of host devices and enables data sharing by a data storage device, through management of allocation information and access mode information of memory regions included in the data storage device used by the plurality of host devices, thereby improving data processing performance by the plurality of host devices and the use efficiency of the data storage device.

Controller, data storage system and computing system

A memory system includes at least one memory device that includes memory areas. The memory system includes a device allocation manager and security erase circuitry. The device allocation manager determines which of the memory areas is allocated or released based on a request input from at least one host. The security erase circuitry stores a security erase task for a first memory area, which is associated with a release determined by the device allocation manager, in an erase job queue, and removes the security erase task from the erase job queue when the first memory area is reallocated to a first host to which the first memory area was allocated before the release.

Apparatus and method for sanitizing a shared memory device or a memory expander

A data processing system includes data processing devices each including a computing memory and configured to perform a task; one or more host devices connected to the data processing devices, and each configured to: select one or more of the data processing devices based on meta information including a size of a memory, and sizes of the computing memories of the respective data processing devices, and request the selected processing devices to perform a first task; a network switch configured to connect the one or more host devices to the data processing devices; and a network manager in the network switch and configured to: collect free memories of the respective data processing devices based on the meta information and the sizes of the computing memories of the respective data processing devices, and control the one or more host devices to use some of the free memories.

Data processing system and operating method thereof

A data storage device includes a shared command queue, a queue controller, a processor, and a memory. The command queue is configured to queue a plurality of jobs transmitted from a plurality of host processors. The queue controller is configured to classify the plurality of jobs into a plurality of levels of jobs according to priority threshold values and assign jobs of the plurality of levels of jobs the processor. The processor is configured to process the jobs assigned by the queue controller. The memory may store data needed to process the job.
