Abstract:
A data storage device includes a filter, a central processing unit (CPU), a first memory configured to store a page, a second memory, and a page type analyzer configured to analyze a type of the page output from the first memory and to transmit an indication signal to the CPU according to an analysis result. According to control of the CPU that operates based on the indication signal, the filter passes the page to the second memory or filters each row in the page, and transmits first filtered data to the second memory.
Abstract:
An operating method of a memory controller includes generating a random value using a seed, generating encrypted intermediate data by encrypting plaintext data using the random value, and storing the seed and the intermediate data in a memory device. Ciphertext data is generated using the seed and the intermediate data based on Ring Learning with Error (RLWE).
Abstract:
A data storage device includes a central processing unit (CPU) executing an application and a hardware filter. A method of operation the data storage device may include initializing the hardware filter based on initialization information corresponding to a changed application when the application is changed so that the hardware filter supports the changed application, filtering read data that is output from a second memory based on filtering condition data, outputting the filtered data using the hardware filter that has been initialized, and transmitting the filtered data to a host via a first memory.
Abstract:
An all-in-one data storage device includes a secondary memory providing read data in response to a read command, an internal hardware filter that filters the first read data according to filtering condition data in order to output filtered data, a primary memory, a host controller, and a memory controller that stores the filtered data in the primary memory and thereafter communicates the filtered data to the host controller.
Abstract:
A data storage device is configured to perform data de-duplication. A method of operating the data storage device includes receiving a first command and write data output from a host and storing the write data in a volatile memory in response to the first command, and writing the write data stored in the volatile memory in a non-volatile memory in response to a second command output from the host.
