Product Summary

The U6264ADC is a static RAM manufactured using a CMOS process technology with the following ope-rating modes: Read, Standby, Write and Data Retention. The memory array is based on a 6-transistor cell. The U6264ADC is activated by the rising edge of E2 (at E1 = L), or the falling edge of E1 (at E2 = H). The address and control inputs open simultaneously. According to the information of W and G, the data inputs, or outputs, are active. During the active state (E1 = L and E2 = H), each address change leads to a new Read or Write cycle. In a Read cycle, the U6264ADC data outputs are activated by the falling edge of G, afterwards the data word read will be available at the outputs.
