HIGH-SPEED 4K x 8 DUAL-PORT STATIC SRAM The **IDT7134SA55J** is a high-speed **1K x 8 Dual-Port Static RAM (SRAM)** manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:
### **Specifications:**
- **Memory Size:** 1K x 8 (8K bits)
- **Organization:** Dual-port (independent read/write ports)
- **Supply Voltage:** 5V ±10%
- **Access Time:** 55ns (max)
- **Operating Temperature Range:** Commercial (0°C to +70°C)
- **Package:** 48-pin **PLCC (Plastic Leaded Chip Carrier)**
- **I/O Type:** TTL-compatible
- **Power Dissipation:** Active – 1W (max), Standby – 100mW (max)
### **Descriptions:**
- The **IDT7134SA55J** is a **dual-port SRAM** that allows simultaneous access from two independent buses.
- It is designed for applications requiring high-speed data sharing between processors or systems.
- Features **on-chip arbitration logic** to prevent data corruption during simultaneous writes to the same address.
- Suitable for **FIFO buffers, shared memory systems, and multiprocessor communication**.
### **Key Features:**
- **True Dual-Port Operation** – Independent read/write on both ports.
- **Bus Compatibility** – TTL-level inputs/outputs.
- **Automatic Power-Down** – Reduces power consumption when not in use.
- **Interrupt Flag** – Supports mailbox communication between ports.
- **Semaphore (Hardware Lock)** – Ensures controlled access to shared resources.
- **High-Speed Access** – 55ns maximum access time.
- **Industrial-Grade Options Available** (e.g., **IDT7134LA55J** for -40°C to +85°C).
This device is commonly used in **telecommunications, networking, and embedded systems** requiring fast, shared memory access.
