Body memory, electronic digital products or devices (such as cell phones, MP3, computers, etc.) itself with the internal storage media, by the memory chip directly installed in the instrument or device to support the normal operation of the machine, used to temporarily store computing data, as well as data exchanged with external memory.
Operating memory, also known as the main memory, the memory required for program operation, can only temporarily store data for the exchange of cache data with the CPU, generally refers to the random access memory (Random Access Memory, RAM).
Extended Information
Memory is not all used to store program files. In contrast to RAM sticks, body memory is mostly used to represent small mobile digital products. Memory is widely used and very important, it can record the human brain can not remember things, to the role of the memo, such as digital products, medical equipment, etc. are to use memory to record images or data, is the most common storage method.
RAM can be divided into two categories: the main memory, which is used to save a variety of processors need to use the data, you can speed up the computer's computing speed; video memory, which is used to save the graphics information that will be displayed on the monitor, you can make the display speed greatly accelerated. The main memory can be divided into SRAM and DRAM.
For DRAM, the capacitor must be charged every time it is actually discharged for each read to ensure the validity of its contents, and even if it is not read, it needs to be refreshed every 15 milliseconds, which makes it the cheapest of the RAMs.
