Abstract
Apparatus which reduces the cycle sequences of a buffer in order to meet high data merge rates by selective control of the chip enable inputs of a plurality of memory chips. During a write ones merge cycle, data patterns from a data-in register control the chip enable inputs of the memory chips and, simultaneously, a common data input line connected to the memory chips is held at logic one. After allowing sufficient time for address decoding of selected memory chips, a common memory write line of the memory chips is enabled to write ones into the selected words of the selected memory chips, while all the other memory chips are undisturbed since their chip enable inputs have not been activated.
