"Why is NAND used in cameras?" Lowest cost per bit. Because it is organized more like a disk with sectors and all, it is useful only for storage. For what it is worth, the problem that I have seen with battery life in digital cameras is that they typically use voltage regulators instead of DC/DC converters, so they don't use the power in the battery very efficiently. LDO regulators are a couple of bucks cheaper than DC/DC converters, though...

Petz, use Ni-Mh batteries. They last 10x as long in digital cameras for some reason. C

Petz, Correct me if I'm wrong, but I think NOR flash has lower power consumption for writes and is faster, but NAND is cheaper. I am really, really disappointed in the battery life on my digital camera and wonder whether NOR could replace NAND in some applications. Why is NAND used in cameras? I don't know much about flash, so I'm the wrong guy to ask. But, I do remember seeing a couple dissertations on the subject on this thread in the past. If I remember correctly, NAND is preferred for storing data, while NOR is better for code. So, I would guess that NAND is higher density, while NOR is faster, but I just don't know. But, that seems to make sense, if you consider the layout of NAND and NOR gates. Pravin.
