Disclosed is a storage device which includes nonvolatile memory devices each including a plurality of memory blocks, a memory controller that controls the nonvolatile memory devices, and a buffer memory that buffers data to be written in the nonvolatile memory devices. In an on-time erase operation, the memory controller controls the nonvolatile memory devices such that an erase operation is performed in a memory block for each of the nonvolatile memory devices. When an early erase condition is satisfied, the memory controller selects nonvolatile memory device among the nonvolatile memory devices and controls the selected nonvolatile memory device such that the erase operation is performed in a memory block of the selected nonvolatile memory device. When a free capacity of the buffer memory is smaller than a first threshold value, the memory controller determines that the early erase condition is satisfied.

Storage device and operating method of storage device

A storage controller includes: (i) a queue monitoring circuit configured to generate monitoring information about a queue depth (QD) for each of a write command and a read command, (ii) a surge detection circuit configured to generate command-by-command surge information based on the monitoring information, (iii) a priority determination circuit configured to generate priority determination information indicating any one of the write command, the read command, and a default according to the command-by-command surge information, and (iv) a priority reflection circuit configured to variably set each of a priority of the write command and a priority of the read command according to the priority determination information.

Storage device, storage controller, and operating method of storage controller

The disclosure relates to a 5th-generation (5G) or 6th-generation (6G) communication system for supporting a higher data transmission rate. A method performed by a first user equipment (UE) in a wireless communication system in which cross-link interference (CLI) exists is provided. The method includes receiving, from a base station, control information related to automatic gain control (AGC) tuning and CLI measurement, receiving, from a second UE, a first signal for the AGC tuning based on the control information, controlling an input signal level of an analog-to-digital converter (ADC) in the first UE based on the first signal, receiving, from the second UE, a second signal for the CLI measurement based on the control information, and transmitting, to the base station, a report message including a CLI measurement result measured based on the second signal.

Communication method and device in wireless communication system having cross-link interference

Disclosed is an operating method of a storage controller communicating with a host and memory regions, which includes receiving a write request for a first memory region of the memory regions from the host, determining the first memory region as unavailable, based on a status information set, generating redirection information indicating that a second memory region of the memory regions is selected instead of the first memory region, performing a write operation in the second memory region based on the redirection information, updating status information of the second memory region in the status information set based on the write operation, outputting redirection result information indicating that write data of the write request are processed in the second memory region, to the host, and receiving a read request corresponding to the write data and including information of the second memory region from the host.

Storage controller redirecting write operation and operating method thereof

Disclosed is an operating method of a storage device which includes a plurality of nonvolatile memory chips. The method includes providing, at the storage device, information of a capacity of each of the plurality of nonvolatile memory chips to an external host device, receiving, at the storage device, information of a plurality of groups from the external host device, performing a reset after receiving the information of the plurality of groups, mapping, at the storage device, the plurality of nonvolatile memory chips with the plurality of groups, and configuring the plurality of nonvolatile memory chips so as to correspond to the plurality of groups, after performing the reset.

Storage device, operating method of storage device, and electronic device including storage device

An operation method of a storage device configured to communicate with an external device through an interface channel includes receiving an indicator of a first throttling level of a plurality of throttling levels from the external device, setting a first operation parameter based on a throttling predefined table (PDT) including a relationship between the plurality of throttling levels and a plurality of throttling performances, such that the interface channel has a first throttling performance from among the plurality of throttling performances, the first throttling performance corresponding to the first throttling level, receiving a first input/output (I/O) request from the external device through the interface channel having the first throttling performance caused by the setting of the first operation parameter, and processing a first operation corresponding to the first I/O request through the interface channel having the first throttling performance.

Operation method of storage device, and operation method of storage system including host device and storage device

An method of a storage device configured to communicate with an external device through an interface channel includes: storing a throttling predefined table (PDT) including a relationship between target performances and workload characteristics; detecting that a first workload characteristic has changed; determining whether to update the PDT; when it is determined to update the PDT, monitoring a performance of the storage device; updating the PDT to include at least one new value for the workload characteristics and an additional target throttling performance value, based on a calculated monitored performance and the changed value of the first workload characteristic; controlling an operation parameter based on the updated PDT such that the interface channel has a first throttling performance corresponding to the additional target throttling performance value; receiving a first request through the interface channel from the external device; and processing the first I/O request through the interface channel.
