DescriptionUniform Sector Dual and Quad Serial Flash
Datasheet SummaryAI
1. Device Overview:

️· Document Type: This appears to be a technical datasheet or specification for a GigaDevice flash memory chip (GD25VE20C - likely).
️· Function: The chip provides non-volatile storage.
️· Key Features: Quad operation, Status Register protection, and various memory protection options.

2. Memory Protection (Status Register & Block Protect):

️· Block Protect (BP4-BP0): Non-volatile bits in the status register that control the protection of memory areas against programming and erasing. These are written using the Write Status Register (WRSR) command. Different combinations of BP bits, in conjunction with CMP, define the size of protected memory.
