PSP2 Won't Have UMD?
GamersReports revealed an info from a Japanese website stated that
Samsung is making NAND ("Not AND", see below) Flash Memory for the PSP2. And for more
surprising info is that Samsung also told the next Sony's PSP won't use
UMD but using their flash memory as the 'hard drive'. ...
Note from Auri: I find this hard to believe due to the need for PSP2 to run PSP1 games.
Here's the web site this report is based on.
Definitions of NAND on the Web:
a
type of flash memory commonly used for mass storage application like
digital cameras and MP3 players. NAND is a serial memory cell that has
1 less contact per pair of cells than NOR memory making NAND less
expensive to produce.

are very popular, because they use only two transistors instead of the
three in an AND gate yet provide just as much functionality. In
addition, the processor uses gates in combination to perform arithmetic
functions; it can also use them to trigger the storage of data in
memory.

Sheffer stroke, |, also called joint denial and in Boolean algebra and
digital circuitry known as the NAND (Not AND) operation, is a logical
operator which is the negation of the conjunction operator. It can be
used by itself, without any other logical operator, to constitute a
logical formal system. It is named for Henry M. Sheffer, who proved
that all the usual operators of logical calculus (not, and, or,
implies) could be expressed in terms of it.
