Newer synchronous static RAM chips overlap reads and writes. The 0 or 1 state can be written and read instantly without waiting for a capacitor to fill up or drain however, the six transistors take more space than dynamic RAM cells made of one transistor and one capacitor (see dynamic RAM).Įarlier asynchronous static RAM chips performed read and write operations sequentially. Static RAM is fast because the six-transistor configuration of its pretzel-like flip-flop circuits keeps current flowing in one direction or the other (0 or 1). Static RAM chips have access times in the 10 to 30-nanosecond range, while dynamic RAM is usually above 50 ns. In contrast, the main memory in a computer is typically dynamic RAM (DRAM). Static RAM (SRAM, S-RAM) is used for high-speed registers, caches and relatively small memory banks such as a frame buffer on a graphics card.
