Abstract
The present invention relates to a method of writing or reading a semiconductor random access memory (DRAM or SRAM) having plural sense amplifiers connected to lines and having data bus read and write amplifiers, comprised of providing a pair of data buses for access by each sense amplifier and each read and write amplifier, reading or writing one data bus while precharging the other data bus during a first read or write cycle, and reading or writing the other data bus while precharging the first data bus in a second read or write cycle following the first read or write cycle.
