SRAM takes about 6 transistors to make up one storage location; while
Flash like DRAM takes only 1 transistor, hence higher capacity. And
there are other tricks that can boost Flash capacity even further.
I have explained in a separate message, why Flash does not need continued
supply to maintain the info.
Currently, DRAM prices are about 4-5$ per Megabyte, while Flash prices are
approx. 20$ Megabyte (?) and there is a potential for this gap to narrow
because Flash does not even have as big a market as DRAM yet. Digital Cameras and
Audio Recorders/Answering Machines/Cell Phones besides Palmtops like OG 100
are expected to expand the market and thus narrow the price gap. Currently,
the market size for DRAM vs Flash could be 100:1 or even 1000:1 !!!
I am showing this comparision here because from manufacturing point; the cost
is not very different for these two types of memory.
