Sharp – Nor type only ! Boot block type 1.) Every block size different : For different software application 2.) Top boot : Software start from top block Bottom boot : Software start from bottom block Symmetrical type : Every block is the same
Flash unit 1M Byte = 8M bit 2M Byte = 16M bit 4M Byte = 32M bit Note : B = Byte / b = bit
BGA/CSP application – Most for handheld or smaller products For example : Mobile phone, MP3 player DSC, GPS, PDA….. TSOP application – For example : N/B BIOS, Cable/ADSL/VOIP modem, STB,DVD player….
