The MX35UFxGE4AD is a 1.8V 1Gb/2Gb/4Gb SLC NAND Flash memory device with Serial interface. The memory array of this device adopted the same cell architecture as the parallel NAND, however implementing the industry standard serial interface. An internal 8-bit ECC logic is implemented in the chip, which is enabled by default. The internal ECC can be disabled or enabled again by command. When the internal 8-bit ECC logic is disabled, the host side needs to handle the 8-bit ECC by host micro controller. The device supports conventional read mode and continuous read modes. If the configuration register bit "CONT" = 0, the device is in conventional read mode which user cannot read across a page without page read command. If the configuration register bit "CONT" = 1, the device is in continuous read mode which user can read consecutive page across page boundary without next page read command.
Considering user effort reduction, the device provides 40 links of BBM (Bad Block Management), which can provide the continuous good blocks to save software effort and increase read throughput. Moreover, user may enhance the P/E endurance cycle of single block by using more than one BBM links for block replacement to same single block. For example, using two BBM links for same single block replacement which may double the P/E cycle of the same single block, using three BBM links may get triple P/E cycle and so on
