A storage device is provided. The storage device includes a controller which receives a command from a host for instructing performance of a first computation, a non-volatile memory which stores a plurality of datasets, a buffer memory to which a first dataset among the plurality of datasets stored in the non-volatile memory is provided in response to the command, and an accelerator which performs the first computation corresponding to the command, using the first dataset provided to the buffer memory. The accelerator includes a memory access module which receives a first input query for instructing the first computation and the first dataset from the buffer memory, and a first computing module which is connected to the memory access module and determines first final candidate data corresponding to the first input query, using the first dataset.

Storage device and memory system

A serial comparator for comparing serially input data values with an internal data value in order to determine a command implementation requirement, having NOR gates for logic-adding two input data under the control of an output value obtained through an exclusive NOR gate, an inverter and a NAND gate, two latching circuits for latching the output from the NOR gate, two inverters for inverting the outputs from the latching circuits, and a NOR gate for outputting the equivalent value out of the inverted outputs from the two inverters, to output the lowermost bit value as a feedback to the NAND gate so as to output the uppermost address bit value. Accordingly, even in the case where the bit numbers of the input data and the internal data are variable, the operating characteristic becomes adapted to the semiconductor in which the input or output is carried out serially.
