The 6264 is a static random-access memory (SRAM) integrated circuit. It is a volatile semiconductor memory that stores data using flip-flop circuits rather than the capacitors used in dynamic RAM. ### Q: How does the 6264 differ from other SRAM models like the 6116? While both are SRAM chips, the 6264 is a distinct integrated circuit model within the same hardware family. The source material identifies the 6116 specifically as having a storage capacity of 16,384 bits, whereas the 6264 is listed as a separate common variant within this chip series. ### Q: Does the 6264 require memory refreshing? No, as an SRAM chip, the 6264 uses bistable flip-flop circuits to store data. This architecture ensures data remains stable as long as power is supplied, eliminating the need for the periodic refresh cycles required by dynamic RAM. ### Q: In which applications is the 6264 typically used? The 6264 is used in applications requiring high-speed data access, such as cache memory, CPU registers, and hard drive buffers. Its technology is fundamental to personal computers and embedded systems where latency must be minimized. ## Why It Matters The 6264 serves as a specific, tangible implementation of static random-access memory architecture, a technology critical to the performance of modern computing. By utilizing flip-flops instead of capacitors, this integrated circuit model provides the immediate data access speeds necessary for cache memory and high-performance processing tasks. It represents the practical application of SRAM technology that bridges the gap between high-speed CPU operations and slower main memory, playing a vital role in system hierarchies where reducing latency is more important than density or cost. ## Notable For - **Flip-Flop Architecture:** Notable for using bistable flip-flop circuits to store bits, distinguishing it from capacitor-based DRAM. - **High-Speed Access:** Recognized for providing faster access times compared to dynamic memory solutions. - **Industry Classification:** Specifically cataloged under the UNSPSC code 32101603 for procurement and standardization. - **Global Documentation:** Maintains a presence across multiple Wikipedia language editions (English and German) and Wikimedia Commons. ## Body ### Identity and Classification The 6264 is explicitly defined as an **integrated circuit model** and a direct subclass of **static random-access memory (SRAM)**. It falls under the broader umbrella of semiconductor memory and volatile random-access memory. In industry standardization systems, SRAM technology, including the 6264, is assigned the **UNSPSC code 32101603**. The entity is cross-referenced with the **Freebase ID `/m/09djpk`** and is categorized under the **Commons category "6264 (SRAM)"**. ### Technical Architecture The 6264 operates on the principles of static random-access memory technology.
