Embedded Systems Design Europe - May 2008 - (Page 36) memory To NAND or NOR. That is the question. Different applications and functions should be handled with different types of flash memory. Employ the proper flash memory in your design BY VIJAY K. DEVADIGA I 36 n their search for the perfect ‘universal memory’, designers of embedded systems are like characters from the play Waiting for Godot. They’re waiting for an off-stage character, Godot’, to come on stage, meanwhile speculating which of the current or new characters appearing on stage are Godot. From it’s inception in the 1970s, the embedded systems industry as we know it as always been waiting for an off-stage semiconductor-based character named ‘universal memory’ to come along and replace the memory hierarchy inherited from mainframes, minicomputers, and desktop computers: nonvolatile hard disk drives for long term mass storage and backup, dynamic RAM for local fast memory access, and SRAM and ROM for extremely fast access and code storage. This desire has been heightened and intensified as computing as become more embedded, mobile, and portable and candidates for the role of “universal memory” have come on stage. Some – such as EEPROMS, EPROMs, UVEPROMs, ferroelectric RAMs, and various pseudo-RAM combinations – have been turned down. Others such as magnetic RAM are being considered, but are in doubt for a number of economic and technical reasons. However, some of the current characters on the stage – particularly the various flavors of NAND and NOR flash EPROMs – are being touted by their vendors as that offstage character ‘universal memory’, or at least a relative and “close personal friend” including OneNAND, OrNAND, iNAND, GBNAND, moviNAND, ManagedNAND and NANDrive.
