The daily study time is up, because I was on a business trip last week, I was unable to update it in time, Wang Haihan!

SDRAM common sense knowledge popularization
Regarding the basic concept of SDRAM, here is a quote from the article "The Ultimate Memory Guide", "SDRAM (Synchronous Dynamic Random Access Memory), Synchronous Dynamic Random Access Memory. Synchronization means that Memory work requires a synchronous clock, internal commands. The transmission and data transmission are based on it; dynamic means that the storage array needs to be constantly refreshed to ensure that the stored data is not lost, because the data stored in the SDRAM is operated by a capacitor, and it is known that the capacitor is placed in a natural state. If there is discharge, if the power is discharged, it means that the data in the SDRAM is lost. Therefore, the SDRAM needs to be refreshed before the power of the capacitor is discharged. Random means that the data is not stored linearly, but the data is freely specified. Read and write." This is just a introduction to the concept of SDRAM. Let's take a brief look at the internal structure of SDRAM. For the content structure of SDRAM, it is like the Excel table:

SDRAM pin introduction
To talk about SDRAM pins, you must look at the SDRAM datasheet.

Learn the configuration process of SDRAM initialization
For the initialization, it is also necessary to refer to the official documentation.
Eye protection:The principle of chlorophyll defocusing is adopted to prevent the eyeball from focusing for a long time, effectively alleviate eye fatigue, and achieve better eyesight protection.
Anti-blue light, ultraviolet light:The Green Light Film can actively filter the target wavelength while providing a band in the range of 380-400nm. It can effectively block 100% harmful light.
Edge coverage:The soft material fully covers the edges of any device, so it can be affixed to curved screen and round edges, 100% provides excellent edge coverage, and there is no gap between the edges of the device.
Oleophobic and waterproof:The oleophobic coating surface of the Green Light Screen Protector can provide your phone with oleophobic and waterproof properties, which can prevent sweat, grease residue, and fingerprints.
Sensitive touch:The 0.14mm ultra-thin film does not interfere with the touch response, almost as if it does not exist. When using a mobile phone, the fingertips can be easily swiped, bringing you a comfortable gaming experience.
