Embodiment Construction

[0010]Referring to FIG. 1, FIG. 1 shows a block diagram of a memory device according to an embodiment of the present invention. The memory device 10 includes a memory controller 102, a calculation memory 104 and a functional circuit 106. The memory device 10 may be used for implementing some specific calculations, e.g., convolution, of a neutral network and obtaining results(s) of interest by analyzing the calculation results.

[0011]The memory controller 102 is coupled to the calculation memory 104 and the functional circuit 106, and is configured to control the operation of the calculation memory 104 and the functional circuit 106.

[0012]The calculation memory 104 may be a non-volatile memory, for example, NAND flash memory, NOR flash memory and phase change memory. In an embodiment, the calculation memory 104 includes a number of memory cells C11˜Cmn, wherein m and n are positive integers. Each of the memory cells may include a resistor. The resistance of each of the resistors repre...
