Memory and foundry drive investment growth in 2010
According to a Wall Street analyst, semiconductor fixed asset investment in 2010 may reach US$33.5 billion, a 50% increase over 2009, driven again by memory and foundry industries.
Due to the tight capacity of memory in 2009, manufacturers began to increase investment in 2010 to meet the increase in market demand. According to the forecast of Barclays Capital analyst CJ Muse, investment in the semiconductor industry increased by 42% in 2010. By comparison, memory increased by 38% compared with 2009, but decreased by 63% compared with 2007.
Foundry investment will rise from US$5 billion in 2009 to US$9 billion in 2010. It is expected that investment will be concentrated in TSMC and new plants Globalfoundries and Samsung, all of which want to expand their market share in foundry.
Muse predicted in October last year that global semiconductor industry investment would reach US$31 billion in 2010, a year-on-year increase of 45%.

Using RAM for USB and Ethernet in LPC2378
LPC2378 has 58KB RAM, which consists of internal 32KB RAM, 8KB USB RAM, 16KB Ethernet RAM and 2KB RTC RAM.
The 2KB RTC BATTERY RAM has not been tested, but I think it should be usable directly.
For USB and Ethernet RAM, you can use them by simply performing the following operations.
1. Set the PCENE

S3C2440 memory status when booting from NAND FLASH or NOR FLASH
1. When booting from NANDFLASH, when ARM is powered on, ARM will automatically copy the first 4K of NANDFLASH to the S3C2440 internal SRAM, and map the address of SRAM to 0X00000000. After ARM is powered on, it will start running from SRAM.
2. When booting from NOR FLASH, because NORFLASH is connected to

How to use the PIC microcontroller's data memory RAM as a register
PIC16C5X uses the data memory RAM as registers to make addressing simple and clear. They can be divided into operation registers, I/O registers, general registers and special function registers in terms of function. Their organizational structure is shown in Figure 1.4: These registers are represented by codes F0~F79.
