The 74LS170 is a high-speed, low-power 4 x 4 Register File organized as four words by four bits. Separate read and write inputs, both address and enable, allow simultaneous read and write operation. Open-collector outputs make it possible to connect up to 128 outputs in a wired-AND configuration to increase the word capacity up to 512 words. Any number of these devices can be operated in parallel to generate an n-bit length. The 74LS670 provides a similar function to this device but it features 3-state outputs

Applications :-

Random access register files are suitable for scratch-pad memories. This function is useful for communication between different controllers or processors or as a temporary fast storage.
