Flash memory and mobile phones: NOR and NAND have equal chances
The basic wisdom of the flash market is that NOR flash is NOR flash and
NAND flash is NAND flash and the two of them will never meet. Reality, however,
shows a completely opposite state of affairs: both of these types of flash memory
are used in mobile phones, moreover, NAND flash begins to crowd out NOR flash
in the traditional domain: code storage. Which of these types of flash memory is still
will dominate? ISuppli analysts suggest that no.
Most of today’s mobile phones use NOR flash for storage
code, and SRAM or Pseudo SRAM – as buffer or “working” memory.
However, new generation 2 phones.5 and 3 have special requirements for memory,
moreover, it is NAND flash that is used as an alternative. For no one already,
it is probably no secret that new phones will act as more than just communication
devices, but also as MP3 players, PDAs, digital photo and video cameras, then
is, the requirements for processing and storing data are rapidly changing, which creates
new ground for the competition between manufacturers of flash memory of two types: with
one side – Intel and Spansion, voting to use the “NOR-flash+
SRAM or PSRAM “, on the other hand – Samsung, Toshiba and others like them, offering
combination “NAND-flash + SDRAM”.
From this point of view, NAND flash is more profitable because its price is 30% less,
than NOR-flash of the same density – even though recently the price
NAND flash is growing. On the other hand, NAND flash can be used to store
both code and data is another advantage of this type of memory. Samsung and
Toshiba uses a “shadow” architecture when data and code to be
processing, loaded from NAND flash to SDRAM. This approach besides the low price
solutions assumes high performance when working with multimedia
applications due to the high speed of SDRAM. The biggest disadvantage of this
combination is the delay that occurs when data is transferred from NAND flash to
SDRAM and high power consumption, so it can be a repulsive factor
for mobile phone manufacturers.
In other words, the economic factor is “offset” by productivity,
that is, this is why the winners and losers in the struggle for market leadership
there will be no mobile phones. Further, since for phone manufacturers
performance is much more important than price, NOR / SRAM / PSRAM combination is preferred.
Since both combinations can coexist on the market, the optimal configuration
memory for the high-end phone market – a combination of NOR flash and NAND flash.
One example of a successful combination is the Samsung SGH-E100,
which uses an MCP chip combining 128 Mbit NOR flash for storage
code, 128 Mbit NAND-flash for data storage and PSRAM as “working” memory.
