Description and Introduction

CMOS Static RAM 1 Meg (128K x 8-Bit) Revolutionary Pinout The IDT71124S15Y is a high-speed 16K x 8 dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 16K x 8 (131,072 bits)  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 15 ns  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 48-pin CerDIP (Ceramic Dual In-line Package)  
- **Power Consumption:**  
  - Active: 1.5W (max)  
  - Standby: 0.5W (max)  

### **Descriptions:**
- The IDT71124S15Y is a dual-port SRAM that allows simultaneous access from two independent ports, making it ideal for multiprocessor systems, communication buffers, and other applications requiring shared memory.  
- It features fully independent control, address, and I/O pins for each port, enabling true asynchronous operation.  
- Includes built-in arbitration logic to prevent data corruption during simultaneous write operations to the same memory location.  

### **Features:**
- **True Dual-Port Operation:** Independent read/write access from both ports.  
- **High-Speed Performance:** 15 ns access time for fast data processing.  
- **Bus Compatibility:** TTL-compatible inputs and outputs.  
- **On-Chip Arbitration:** Automatic conflict resolution for simultaneous writes.  
- **Low Power Consumption:** Standby mode reduces power usage.  
- **Industrial-Grade Reliability:** Robust design for stable performance.  

This information is based solely on the manufacturer's specifications for the IDT71124S15Y.
