General Description
DS1609 General Description
The DS1609 is a random access 256byte dual port memory designed to connect two asyncronous address/ data buses together with a common memory element. Both ports have unrestricted access to all 256 bytes of memory, and with modest system discipline no arbitration is required. Each port is controlled by three control signals: output enable, write enable, and port enable. The device is packaged in plastic 24pin DIP and 24pin SOIC. Output enable access time of 50 ns is available when operating at 5 volts.
