Embodiments of the present disclosure relate to a system and an operating method of the system. Based on some embodiments of the disclosed technology, the system may include a random access memory structured to include memory cells to store data, a cache memory configured to cache at least part of the data, and a processor in communication with the random access memory and the cache memory to access at least part of the data from the random access memory or cache memory. The system may determine a cache hit ratio for the cache memory, and may set an operating frequency of the random access memory based on the cache hit ratio.

System setting including operating frequency of random access memory based on cache hit ratio and operating method thereof

A memory module includes a plurality of first memory chips and a second memory chip. Raw data is stored in the plurality of first memory chips. Parity data generated based on the raw data is stored in the second memory chip. Each of the first memory chips and the second memory chip is configured to exchange data with a controller based on a burst length unit. The second memory chip stores a first parity data generated from the raw data by a first error correction method, and stores a second parity data generated from the raw data and the first parity data by a second error correction method.

Memory module for detecting and correcting a row direction error and a column direction error

The present technology relates to an electronic device. According to the present technology, a memory controller may include a training controller, a training data storage, and a machine learning processor. The training controller may perform training of correcting interface signals exchanged with a memory device, generate training data that is a result of the training, and output the training data as sample training data based on a comparison result of a training reference and the training data. The training data storage may store training history information including plural pieces of sample training data. The machine learning processor may update the training reference through machine learning based on the training history information.

A data storage device includes a processor and a non-volatile memory. The processor compares a data processing size of a first command received from the host at a first time point with a reference size and divides the first command into a plurality of sub-commands when the data processing size is greater than the reference size. The data storage device further includes a memory that includes a first queue and a second queue.

Data storage device that divides and processes a command and data processing system including the same

Embodiments of the present disclosure relate to an outdoor unit of an air conditioner configured to cool a heating unit by making contact with the heating unit, a cooling unit applied thereto, and a method for manufacturing the cooling unit. An outdoor unit of an air conditioner comprises a compressor configured to compress refrigerant; a condenser configured to condense the refrigerant discharged from the compressor; a control box provided with an electronic component configured to control an outdoor unit of an air conditioner; and a cooling unit configured to cool a heating unit by making contact with the heating unit of the electronic component, wherein the cooling unit comprises a heat radiating member having one side thereof make contact with the heating unit; and a refrigerant pipe extended by penetrating through the heat radiating member and in which refrigerant is moved.

Outdoor unit of air conditioner, cooling unit applied thereto, and method for manufacturing cooling unit

An oscillator auto-trimming method is provided. The oscillator auto-trimming method includes receiving, by a subtractor, a first count result and second count result to output a difference between the first count result and the second count result as an offset frequency, receiving, by a divider, the offset frequency to output a divided signal corresponding to a result of dividing the offset frequency by a reference offset frequency output from a micro control unit, and receiving, by the micro control unit, the divided signal and determine whether to change an oscillator frequency.
