MEMORY DEVICE AND OPERATION METHOD THEREOF

A memory device and an operation method thereof are provided. The operation method includes: encoding an input data, sending an encoded input data to at least one page buffer, and reading out the encoded input data in parallel; encoding a first part and a second part of a weight data into an encoded first part and an encoded second part of the weight data, respectively, writing the encoded first part and the encoded second part of the weight data into a plurality of memory cells of the memory device, and reading out the encoded first part and the encoded second part of the weight data in parallel; multiplying the encoded input data with the encoded first part and the encoded second part of the weight data respectively to parallel generate a plurality of partial products; and accumulating the partial products to generate an operation result.
