So, I looked up my samsung chips on my rite aid cam, and they seem to be different than others posted.

Here are the chips I have:
K9T1G08U0M
128M x 8 Bits NAND Flash Memory

General Description
Offered in 128Mx8bits, the K9T1G08U0M is 1Gbit with spare 32Mbit capacity.
The device is offered in 3.3V Vcc.
Its NAND cell provides the most cost-effective solutIon for the solid state mass storage market.
A program operation can be performed in typical 200Âµs on the 528-bytes and an erase operation can be performed in typical 2ms on a 16K-bytes block. Data in the page can be read out at 50ns cycle time per byte.
The I/O pins serve as the ports for address and data input/output as well as command input. The on-chip write control automates all program and erase functions including pulse repetition, where required, and internal verification and margining of data. Even the write-intensive systems can take advantage of the K9T1G08U0M's extended reliability of 100K program/ erase cycles by providing ECC(Error Correcting Code) with real time mapping-out algorithm.
The K9T1G08U0M is an optimum solution for large nonvolatile storage applications such as solid state file storage and other portable applications requiring non-volatility.

So... thats a 1GB flash chip, This is secondary storage(disk).

This is the other samsung chip.
K4D551638F-TC50
http://www.samsung.com/Products/Semiconductor/GraphicsMemory/DDRSDRAM/256Mbit/K4D551638F/K4D551638F.htm
General Description
FOR 4M x 16Bit x 4 Bank GDDR SDRAM
The K4D551638F is 268,435,456 bits of hyper synchronous data rate Dynamic RAM organized as 4 x 4,194,304 words by 16 bits, fabricated with SAMSUNG's high performance CMOS technology.
Synchronous features with Data Strobe allow extremely high performance up to 1.1GB/s/chip.
I/O transactions are possible on both edges of the clock cycle.
Range of operating frequencies, programmable burst length and programmable latencies allow the device to be useful for a variety of high performance memory system applications.

TC50 Specific
K4D551638F-TC50
200MHz
400Mbps/pin

SSTL_2
2.6V Â± 0.1V
66pin TSOP-II

So... this is primary storage(system memory), runs at 200mhz.

OS X users might be interested in PureTool since PureTool is no longer being developed.
