To make matters worse, even global giants are now beginning to desert China. Samsung's NAND flash production capacity in Chinese city of Xian accounts for more than 14% of global capacity. False True SRAM: Static Random Access Memory. Manufacturers sometimes add battery power to volatile memory devices to support persistent data storage. In less than a week, China's chip companies took a hammering on the stock market, losing as much as $8.6 billion in market value. e. Non-volatile memory ( NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. Data is accessed by means of a binary number called a memory address applied to the chip's address pins, which specifies which word in the chip is to be accessed. In view of this it is used where data needs to be stored permanently, even when the power is removed - many memory technologies lose the data once the power is removed. If the memory address consists of M bits, the number of addresses on the chip is 2M, each containing an N bit word. S-RAM (Static Random Access Memory)A RAM in which data is preserved so long as electrical power is supplied. The brutal economics of the industry mean fewer companies can afford to keep up. Semiconductor memory technology is developing at a fast rate to meet the For everyone else, including China, its not easy to break in.
