combjelly: Their StrataFlash device is a NOR-type, it just stores 4 levels of voltage per cell, so has roughly twice the number of bits per cell. This conversion takes time and makes it slow, but it sure is cheap per bit... Yes, you are correct. Intel does produce some NOR flash, but then AMD also produces some NAND (UltraNAND product line). That Intel's StrataFlash looks a lot like NAND from a performance perspective is another matter ;) -fyo

Not totally true. Their StrataFlash device is a NOR-type, it just stores 4 levels of voltage per cell, so has roughly twice the number of bits per cell. This conversion takes time and makes it slow, but it sure is cheap per bit... In addition to this, INTC is the world's largest mfg. of "traditional" sectored NOR flash. As of late INTC has been really pushing the strata flash. Unfortunately, it (as of yet) doesn't come in the entire temperature operating range of even -40 to +85deg C, let alone the automobile of -55 to +125 deg C. I recently designed AMD NOR, even sectored CFI, 64Mbit flash memory into my product. Forget write cycles, Intel does not even have a comparative offering. The best they could offer was their strata flash, with read spec down to -40 but write spec only down to -20deg C! They claim that they will offer the entire range of temp only sometime late next year. TG P.S. I did not want to design the "boot sectored" type of memory from either mfg. as it's just more of a hassle handling the uneven boot sectors (for my data storage app).
