Abstract: A method of operating a storage device includes; counting a number of fast cycles for the memory block when a program interval between two successive program operations directed to memory cells of the memory block is less than a minimal program interval, and/or when an erase interval between two successive erase operations directed to the memory block is less than a minimal erase interval, and selecting the memory block to be erased by an erase operation or selecting memory cells of the memory block to be programmed by a program operation in response to the counted number of fast cycles for the memory block.

Abstract: A persistent memory device is disclosed. The persistent memory device may include a cache coherent interconnect interface. The persistent memory device may include a volatile storage and a non-volatile storage. The volatile storage may include at least a first area and a second area. A backup power source may be configured to provide backup power selectively to the second area of the volatile storage. A controller may control the volatile storage and the non-volatile storage. The persistent memory device may use the backup power source while transferring a data from the second area of the volatile storage to the non-volatile storage based at least in part on a loss of a primary power for the persistent memory device.

Abstract: Provided are an accelerator controlling a memory device, a computing system including the accelerator, and an operating method of the accelerator. The accelerator includes: a signal control/monitoring circuit configured to detect an entry to a self-refresh mode of a memory device and an exit from the self-refresh mode based on monitoring a signal provided from a host; an accelerator logic configured to generate a first command/address signal and a first piece of data; and a selector configured to output the first command/address signal and the first piece of data to the memory device based on detection of the entry to the self-refresh mode, and output a second command/address signal and a second piece of data provided from the host, to the memory device, based on detection of the exit from the self-refresh mode.
