分区管理内存配置最初
（在任何分区操作之前）由用户数据区域和RPMB区域分区以及两个引导区域分区组成。嵌入式设备还为主机提供了为不同的使用模式配置具有独立地址空间的额外本地内存分区的可能性，从逻辑地址0x00000000开始。因此，内存块区域可以分类如下：-两个引导区域分区，其大小是128 KB的倍数，可以从e•MMC执行引导。-通过可信机制访问的一个RPMB分区，其大小定义为128 KB的倍数。-四个通用区域分区，用于存储敏感数据或其他主机使用模型，其大小是写保护组的倍数。引导和RPMB区域分区的大小和属性由内存制造商定义（只读），而通用区域分区的尺寸和属性在设备生命周期内只能由主机编程一次（一次性可编程）。此外，主机可以自由地在用户数据区域中配置一个段以实现为增强存储介质，并可以根据写保护组指定其起始位置和大小。
一次性可编程
此增强型用户数据区的属性在设备生命周期内只能编程一次（一次性可编程）。MKEV008GCB-SC510-23-可能的最终配置如下：9.2用户密度 引导和RPMB大小容量引导1大小引导2大小RPMB大小8 GB 4096 KB 4096 KB 扩展CSD中的用户密度大小容量用户区域容量SEC_COUNT 8 GB 7577600 KB（7.22 GB）0xE74000 最大增强分区大小容量最大增强分区尺寸Max_ENH_Size_MUL T HC_WP_GRP_SIZ E HC_ERASE_GRP_SIZ E 8 GB 3875536,8 96字节（3696MB）0xE7h 0x20h 0x1h最大增强区域=Max_ENH_Size_MULT x HC_WP-GRP_Size x HC_ERASE_GRP_ Size x 512k字节MKEV008GCB-SC510-25-9.3引导操作模式在引导操作模式下，在发出CMD1之前，主设备可以通过保持CMD线低或发送带有参数+0xFFFFFA的CMD0从从设备（设备）读取引导数据。根据寄存器设置，可以从引导区或用户区读取数据。
Initial partition management memory configuration
(Before any partition operation) consists of user data area and RPMB area partition and two boot area partitions. The embedded device also provides the host with the possibility of configuring additional local memory partitions with independent address spaces for different usage modes, starting from the logical address 0x00000000. Therefore, the memory block area can be classified as follows: - Two boot area partitions, whose size is a multiple of 128 KB, can be booted from e • MMC- An RPMB partition accessed through a trusted mechanism. Its size is defined as a multiple of 128 KB- Four general area partitions are used to store sensitive data or other host usage models, and their size is a multiple of the write protection group. The size and attributes of the boot and RPMB area partitions are defined by the memory manufacturer (read-only), while the size and attributes of the general area partitions can only be programmed by the host once in the device life cycle (one-time programmable). In addition, the host can freely configure a segment in the user data area to be an enhanced storage medium, and can specify its starting position and size according to the write protection group.
One time programmable
The properties of this enhanced user data area can only be programmed once in the device life cycle (one-time programmable). MKEV008GCB-SC510-23 - The possible final configurations are as follows: 9.2 User Density • Boot and RPMB Size Capacity Boot 1 Size Boot 2 Size RPMB Size 8 GB 4096 KB 4096 KB • Extended CSD User Density Size Capacity User Area Capacity SEC_ COUNT 8 GB 7577600 KB (7.22 GB) 0xE74000 • maximum enhanced partition size capacity maximum enhanced partition size Max_ ENH_ Size_ MUL T HC_ WP_ GRP_ SIZ E HC_ ERASE_ GRP_ SIZ E 8 GB 3875536,8 96 bytes (3696MB) 0xE7h 0x20h 0x1h Maximum enhanced area=Max_ ENH_ Size_ MULT x HC_ WP-GRP_ Size x HC_ ERASE_ GRP_ Size x 512k bytes MKEV008GCB-SC510-25-9.3 Boot operation mode In boot operation mode, before sending CMD1, the master device can read boot data from the slave device (device) by keeping the CMD line low or sending CMD0 with parameter+0xFFFFFA. According to the register settings, data can be read from the boot area or the user area.
