Abstract:
A memory device performing an internal copy operation is provided. The memory device may receive a source address, a destination address, and page size information together with an internal copy command, compares the source address with the destination address, and performs an internal copy operation. The internal copy operation may be an internal block copy operation, an inter-bank copy operation, or an internal bank copy operation. The internal copy operation may be performed with respect to one-page data, half-page data, or quarter-page data, based on the page size information. The memory device may output as a flag signal a copy-done signal indicating that the internal copy operation has been completed.
Abstract:
Memory devices and methods of operating the same are provided. The memory device including at least one internal circuit including a memory cell array and a peripheral circuit configured to drive the memory cell array, a monitor logic configured to monitor a current flowing into the at least one internal circuit and output a monitoring result, a detect logic configured to detect whether a leakage current flows in the at least one internal circuit based on the monitoring result, and output detected information regarding the leakage current, and diagnosis logic configured to diagnose an error in the at least one internal circuit based on the detected information.
Abstract:
A data mask system includes a processor providing control signals including a command signal, an address signal, and a data signal, a data mask processor receiving the control signals and providing either write data or masked data in response to the control signals, and generating data mask information and a data mask selection signal from at least one of the control signals, and a data mask register unit receiving the data mask selection signal, storing the data mask information, selecting a subset of the stored data mask information in response to the data mask selection signal, and returning selected data mask information to the data mask processor. The data mask processor receives the selected data mask information from the data mask register unit and provides the masked data as a result of performing a data mask operation on the data signal according to the selected data mask information.
Abstract:
A device for verifying a circuit design including a first circuit block and a second circuit block includes a verification vector generator and a design verifier. The verification vector generator determines a first verification vector by performing reinforcement learning through neural network computation based on a coverage corresponding to a first test vector, the coverage being determined based on a state transition of the first circuit block generated by inputting the first test vector to the first circuit block. The design verifier performs design verification for the first circuit block by using the first verification vector.
Abstract:
A memory device includes an input/output (I/O) interface, a secure logic for receiving a storage verifying command including an expected value of secure data via the I/O interface, an I/O logic for receiving an input request for inputting user data into the memory device and/or an output request for outputting user data therefrom and perform one of the input request and/or the output request, and a memory unit including a secure area, accessible by the secure logic, for storing the secure data and a normal area, accessible by the I/O logic, for storing the user data. The secure logic reads the secure data from the secure area in response to the input of the storage verifying command and outputs a storage verifying result to the external device, without outputting the secure data to the external device, according to whether the secure data expected value is identical with the secure data.
