A data processing circuit includes a condition input circuit and a search engine array. The condition input circuit receives and stores multiple search conditions corresponding to multiple data search tasks. The search engine array receives the search conditions and performs the data search tasks in a parallel manner according to the search conditions. The search engine array includes a storage medium and multiple search engines. The search condition(s) corresponding to one data search task is provided to one search engine and the search engine array accesses a random access memory to load the data stored in the random access memory into the storage medium. The search engines search the data stored in the storage medium according to the corresponding search condition(s) to perform the corresponding data search task, concurrently, and obtain a corresponding search result.

Data processing circuit and data processing method

A memory controller coupled between an external device and a memory is provided. The memory controller is coupled to the external device via a second interface and coupled to the memory via a first interface. The memory controller further includes a control logic to control the first interface and the second interface. The control logic sets the second interface to be at a receiving mode to receive a test data from the external device, and sets the first interface to be at a transmitting mode to transmit the test data to the memory. After a predetermined time, the control logic sets the first interface to be at the receiving mode to receive a test result from the memory, and sets the second interface to be at a transmitting mode to transmit the test result to the external device.

Memory controller and memory module

A memory controller including a first transmittal module, a clock pin, a second transmittal module, a first control module and a second control module is disclosed. The first transmittal module includes a specific pin. The clock pin receives a clock signal. The first transmittal module and the clock pin constitute an embedded multimedia card (eMMC) interface. The second transmittal module and the clock pin constitute a universal flash storage (UFS) interface. The first control module communicates with an external host via the first transmittal module according to the clock signal when a level of the specific pin is at a first level. The second control module communicates with the external host via the second transmittal module according to the clock signal when the level of the specific pin is at a second level. The first level exceeds the second level.

Memory controller and accessing system utilizing the same

A storage device including a processor, a controller, and a switch is provided. The processor is configured to control a logic circuit. When a main reset signal is enabled, the processor generates a sub-reset signal according to the operation status of the logic circuit. The controller generates a mask signal according to the main reset signal and the sub-reset signal.
