摘要： In one embodiment, the semiconductor device includes a memory array and a control architecture configured to control reading data from and writing data to the memory array. The control architecture is configured to receive data and a codeword location in the memory array, select one or more data units in the received data based on a data mask, read a codeword currently stored at the codeword location in the memory array, error correct the read codeword to generate a corrected read codeword, form a new codeword from the selected data units of the received data and data units in the corrected read codeword that do not correspond to the selected data units, and write the new codeword to the memory array.

摘要： A method of operating a memory device includes: generating an internal read command in response to a received masked write command, the internal read command being generated one of (i) during a write latency associated with the received masked write command, (ii) after receipt of a first bit of masked write data among a plurality of bits of masked write data, and (iii) in synchronization with a rising or falling edge of a clock signal received with an address signal corresponding to the masked write command; reading, in response to the internal read command, a plurality of bits of data stored in a plurality of memory cells, the plurality of memory cells corresponding to the address signal; and storing, in response to an internal write command, the plurality of bits of masked write data in the plurality of memory cells.
