WebEach sector has 256 pages or 65,536 (64K, 0x10000) bytes. Each page has 256 bytes. Therefore, the memory has 16,384 pages or 4,194,304 (0x400000) bytes. The whole memory can be erased using the Bulk Erase instruction, or a sector at a time, using the Sector Erase instruction.
WebAddonics Dual CF-IDE HDD Adapter with 8GB SanDisk Extreme IV CompactFlash. Changing your HDD for a CF boot drive (CompactFlash card on CF-PATA/SATA adapter) is an alternative to using SSD to boost the performance. This is primarily done by ThinkPad X40, X41 and X41 Tablet series owners due to the extremely slow speed of 1.8" HDD. WebIn my experience, all of the older flash chips allow you to change any 1 bit to a 0 bit without an erase cycle, even if that bit is in a page or even a byte that has already had other bits programmed to zero -- a page of flash can be programmed multiple times between erases. (This is called "multiple-write" in the YAFFS article).
