Abstract: A method of reinforcement learning of a neural network device for generating a verification vector for verifying a circuit design comprising a circuit block includes inputting a test vector to the circuit block, generating one or more rewards based on a coverage corresponding to the test vector, the coverage being determined based on a state transition of the circuit block based on the test vector, and applying the one or more rewards to a reinforcement learning.

Abstract: A memory system includes a memory device and a controller. The memory device includes plural storage regions including plural non-volatile memory cells. The plural storage regions have a different data input/output speed. The controller is coupled to the memory device via at least one data path. The controller performs a readahead operation in response to a read request input from an external device, determines a data attribute regarding readahead data, obtained by the readahead operation, based on a time difference between reception of the read request and completion of the readahead operation, and stores the readahead data in one of the plural storage regions based on the data attribute.

Abstract: The present technology relates to an electronic device. According to the present technology, a memory controller may include an attribute determiner configured to determine an attribute of each of a plurality of pages included in a first external device to indicate one of a hot page and a cold page, based on an access interval which is an interval from a time at which data is stored in each of the pages to a time at which access to the data is requested, a page analyzer configured to determine a ratio of hot pages having a hot page attribute to the plurality of pages, and a memory allocator configured to control one of the first external device and the second external device to store therein externally provided data based on the ratio of hot pages.

Abstract: Provided herein may be a memory controller and a memory system including the same. The memory controller includes a scanning period controller configured to reset, whenever scanning points sequentially arrive, access information indicating whether each of a plurality of pages is accessed, and set a scanning interval for each of the pages between the scanning points for the page based on an attribute of the page, an attribute determiner configured to determine, as a hot page or a cold page, the attribute of each of the pages based on an access interval for the page from the first scanning point among the scanning points for the page to time at which access to data stored in the page is requested, and a memory allocator configured to control first and second memory devices based on the attributes of the pages.

Abstract: A storage device is provided to comprise a memory device for storing data, a cache memory device including a first cache memory configured to cache certain data stored in the memory device and a second cache memory configured to store data evicted from the first cache memory, and a memory controller configured to receive a read request for first data from a host, evict second data from the first cache memory based on a reuse distance of the second data, store the second data in the second cache memory, load the first data to the first cache memory, and transmit the first data to the host.
