Abstract:
A memory access command, column address and plurality of write data values are received within an integrated-circuit memory chip via external signaling links. In response to the memory access command, the integrated-circuit memory chip (i) decodes the column address to select address-specified sense amplifiers from among a plurality of sense amplifiers that constitute a sense amplifier bank, (ii) reads first data, constituted by a plurality of read data values, out of the address-specified sense amplifiers, and (iii) overwrites the first data within the address-specified sense amplifiers with second data constituted by one or more of the write data values and by one or more of the read data values.
