Description and Introduction

CMOS Static RAM 1 Meg (128K x 8-Bit) Revolutionary Pinout The part **IDT71124S20Y** is a high-speed 16K x 8 Dual-Port Static RAM manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
- **IDT (Integrated Device Technology)**  

### **Specifications:**  
- **Organization:** 16K x 8 (131,072 bits)  
- **Technology:** CMOS  
- **Speed:** 20 ns access time  
- **Voltage Supply:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 48-pin CerDIP (Ceramic Dual In-line Package)  

### **Descriptions:**  
- **Dual-Port RAM:** Allows simultaneous access from two independent buses.  
- **High-Speed Operation:** Optimized for fast read/write operations.  
- **Low Power Consumption:** CMOS technology ensures efficient power usage.  
- **Fully Static Operation:** No refresh cycles required.  
- **Interrupt Support:** Features BUSY and INT flags for arbitration and communication.  

### **Features:**  
- **True Dual-Port Memory Cells:** Enables independent read/write operations on both ports.  
- **Semaphore Signaling:** Supports hardware-based communication between processors.  
- **Master/Slave Configuration:** Allows expansion for wider word applications.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **On-Chip Arbitration Logic:** Prevents contention during simultaneous access.  

This part is commonly used in applications requiring high-speed data sharing between processors, such as communication systems, multiprocessing, and real-time data processing.  

(Note: Always verify datasheets for the latest specifications.)
