为什么SRAM常用于高速缓冲存储器？
Why SRAM is commonly used in cache memory?
我正在研究RAM，我不明白为什么Static RAM常用于缓存
因为它可以比动态 RAM 更快。而且比较贵，不然到处用。
A memory cache, sometimes called a cache store or RAM cache, is a
portion of memory made of high-speed static RAM (SRAM) instead of the
slower and cheaper dynamic RAM (DRAM) used for main memory. Memory
caching is effective because most programs access the same data or
instructions over and over. By keeping as much of this information as
possible in SRAM, the computer avoids accessing the slower DRAM. †

主要原因是动态 RAM 速度较慢。如您所知，高速缓存用于快速访问，因此通常静态 RAM 是高速缓存的更好选择。
