FORESEE eMMC with powerful L2P (Logical to Physical) NAND Flash management algorithm provides unique functions:

• Host independence from details of operating NAND flash
• Internal ECC to correct defect in NAND flash
• Sudden-Power-Loss safeguard
  To prevent from data loss, a mechanism named Sudden-Power-Loss safeguard is added in the eMMC. In the case of suddenpower-failure, the eMMC would work properly after power cycling.
• Global-wear-leveling
  To achieve the best stability and device endurance, this eMMC equips the Global Wear Leveling algorithm. It ensures that not only normal area, but also the frequently accessed area, such as FAT, would be programmed and erased evenly.
• IDA(Initial Data Acceleration)
  The eMMC prevents the pre-burned data from data-loss with IDA, in case of our customer had pre-burned data to eMMC, before the eMMC being SMT.
• Cache
  The eMMC enhanced the data written performance with Cache, with which our customer would get more endurance and reliability

The embedded device offers also the possibility of configuring by the host additional split local memory partitions with independent addressable space starting from logical address 0x00000000 for different usage models. Default size of each Boot Area Partition is 4096 KB and can be changed by Vendor Command as multiple of 128KB. Boot area partition size is calculated as ( 128KB * BOOT_SIZE_MULTI ) The size of Boot Area Partition 1 and 2 cannot be set independently and is set as same value Boot area partition which is enhanced partition. Therefore memory block area scan is classified as follows:

• Factory configuration supplies boot partitions.
• The RPMB partition is 16MB.
• The host is free to configure one segment in the User Data Area to be implemented as enhanced storage media, and to specify its starting location and size in terms of Write Protect Groups. The attributes of this Enhanced User Data Area can be programmed only once during the device life-cycle (one-time programmable).
• Up to four General Purpose Area Partitions can be configured to store user data or sensitive data, or for other host usage models. The size of these partitions is a multiple of the write protect group. Size and attributes can be programmed once in device life-cycle (one-time programmable). Each of the General Purpose Area Partitions can be implemented with enhanced technological features

Standard export packaging available. Customers can choose from cartons, wooden cases, and wooden pallets according to their requirements.
