The Chinese translation of cache is "cache memory". Its original meaning refers to a kind of RAM whose access speed is faster than that of general random access memory (RAM); it is actually made of DRAM. The large-capacity internal memory is regarded as a high-speed memory and is a small-capacity local memory, generally composed of high-speed SRAM.

The Chinese translation of cache is "cache memory" .
Cache (Cache) is actually a small-capacity local memory set up to treat the large-capacity internal memory composed of DRAM as high-speed memory. It is generally composed of high-speed SRAM.
Cache memory is a small but high-speed memory located between the CPU and the main memory DRAM (Dynamic Random Access Memory). It is usually composed of SRAM (Static Random Access Memory). It is a small-capacity but high-speed memory located between the CPU and the memory.
The speed of the CPU is much higher than that of the memory. When the CPU directly accesses data from the memory, it has to wait for a certain period of time, while the Cache can save a part of the data that the CPU has just used or recycled. If the CPU needs to access data again, When using this part of the data, it can be called directly from the Cache, thus avoiding repeated access to data and reducing the waiting time of the CPU, thus improving the efficiency of the system.
Cache is divided into L1Cache (level one cache) and L2Cache (level two cache). L1Cache is mainly integrated inside the CPU, while L2Cache is integrated on the motherboard or CPU.
