Abstract: A memory module includes a memory device, a command/address buffering device, and a processing data buffer. The memory device includes a memory cell array, a first set of input/output terminals, each terminal configured to receive first command/address bits, and a second set of input/output terminals, each terminal configured to receive both data bits and second command/address bits. The command/address buffering device is configured to output the first command/address bits to the first set of input/output terminals. The processing data buffer is configured to output the data bits and second command/address bits to the second set of input/output terminals. The memory device is configured such that the first command/address bits, second command/address bits, and data bits are all used to access the memory cell array.

Abstract: A memory device includes a memory cell array formed in a semiconductor die, the memory cell array including a plurality of memory cells to store data and a calculation circuit formed in the semiconductor die. The calculation circuit performs calculations based on broadcast data and internal data and omits the calculations with respect to invalid data and performs the calculations with respect to valid data based on index data in a skip calculation mode, where the broadcast data are provided from outside the semiconductor die, the internal data are read from the memory cell array, and the index data indicates whether the internal data are the valid data or the invalid data. Power consumption is reduced by omitting the calculations and the read operation with respect to the invalid data through the skip calculation mode based on the index data.
