Signetics 3101A
The 3101A is a 64-bit, Schottky clamped TTL, ReadWrite Random Access Memory ideal for use in scratch pad and high-speed buffer memory applications. The 3101A is a fully decoded memory array organized as 16 words of 4 bits each, with separate input and output lines. It features PNP inputs, one chip enable line, and open collector outputs for ease of memory expansion.| Part No. | 3101A |

DESCRIPTION
The outputs of the 3101A assume ,a logic "1" state during write. This allows both memory inputs and outputs to share a common bus for minimizing interconnections, and more effective utilization of common I/O circuitry. The 3101A is available in the commercial and military temperature ranges. For the commercial temperature range (DoC to +75°C) specify N3101A, B or F. For the military temperature range (-55°C to +125°C) specify S3101A, F only.FEATURES
