Description and Introduction

HIGH-SPEED 4K x 8 DUAL-PORT STATIC SRAM The IDT7134-SA35J is a high-speed 4K x 8-bit dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 4K x 8-bit (4096 words x 8 bits)  
- **Technology:** CMOS  
- **Access Time:** 35 ns  
- **Operating Voltage:** 5V ±10%  
- **Operating Temperature Range:** 0°C to +70°C (Commercial)  
- **Package:** 48-pin Ceramic DIP (Dual In-line Package)  
- **Power Dissipation:**  
  - Active: 1.5W (max)  
  - Standby: 55mW (max)  

### **Descriptions:**
- The IDT7134 is a **dual-port RAM**, allowing simultaneous access from two separate buses.  
- It features **independent control, address, and I/O pins** for each port, enabling true asynchronous operation.  
- Designed for high-speed applications requiring shared memory access, such as multiprocessor systems, communications, and real-time processing.  
- Includes **on-chip arbitration logic** to prevent data corruption during simultaneous writes to the same location.  

### **Features:**
- **True Dual-Port Operation:** Independent read/write access from both ports.  
- **Bus Compatibility:** TTL-compatible inputs and outputs.  
- **Automatic Power-Down:** Reduces power consumption when not in use.  
- **Semaphore (Flag) Logic:** Supports inter-processor communication.  
- **Expandable Data Width:** Can be cascaded for wider word sizes (e.g., 16-bit, 32-bit).  
- **High Reliability:** Industrial-grade quality with robust noise immunity.  

This device is commonly used in applications requiring high-speed data sharing between processors or systems.  

(Note: Always refer to the official datasheet for detailed electrical characteristics and timing diagrams.)
