Introduction to 7164S85TDB

The 7164S85TDB is a memory chip manufactured by Intel. It is a single-chip, 16M bit (2GB) DRAM (Dynamic Random Access Memory) device designed as a high-performance alternative to standard DRAMs. It features an advanced dataflow architecture and an optimized access time of 45 nanoseconds to perform ultra-fast data transfers.

Application Field of 7164S85TDB

The 7164S85TDB is an advanced memory chip, providing large storage capacity and increased performance over standard DRAMs. It has a wide range of applications in computers, communication systems, networking equipment, image processing systems, and embedded systems.This DRAM is ideal for use in high-end servers and workstations, where large amounts of memory are required and fast access times are critical. It can also be used in embedded and real-time systems, where the quick access times are crucial for efficient data processing and control. Furthermore, the 7164S85TDB is suitable for set-top boxes, digital video recorders, HDTVs, and other digital multimedia applications. It is also suitable for wireless data transfer applications, since its low-power consumption allows for longer battery life and longer device operation.

Working Principle of 7164S85TDB

The 7164S85TDB employs a parallel dataflow architecture, which allows for quick burst access. Each byte is divided into two sub-bytes, called multibus-banks, and the entire data bus is free of wait states. This technology offers increased throughput and reduced latency.The 7164S85TDB\'s optimized access time of 45 nanoseconds enables ultra-fast data transfers. The data is accessed with 4-bit or 10-bit addressing schemes, making it very fast and efficient. The chip also has an auto pre-charge function, which reduces the power consumption significantly.The 7164S85TDB includes several built-in functions to ensure optimum operation. The on-chip ECC (Error Control Coding) circuitry provides error correction for the data stored in memory. The DQM (Data Quality Monitor) monitors and reports on the quality of the data for each block of memory. The CKE (Clock Enable) functionality enables asynchronous clock operation and reduces power consumption.The 7164S85TDB also features an on-chip refresh counter, which automatically refreshes data stored in the DRAM in order to maintain data integrity. This prevents data loss due to power outages, since the refresh counter is reset each time the system is powered up.

Conclusion

The 7164S85TDB is an advanced memory chip manufactured by Intel. It is a single-chip DRAM device that provides ultra-fast data access times, large storage capacity, and efficient operation. Due to its wide range of applications and numerous built-in functions, the 7164S85TDB is a great choice for high-end servers, workstations, and embedded systems.
