In 2004, LHAs were used to transport thousands of Marines and their equipment to Iraq and Afghanistan for combat operations. LHA 6 was placed under contract in June 2007 with NGSB. LHA 6 will be an aviation-centric modified repeat of the USS Makin Island, LHD 8 and is scheduled for delivery to the Navy in 2013.
Phase-change memory (also known as PCM, PCME, PRAM, PCRAM, Ovonic Unified Memory, Chalcogenide RAM and C-RAM) is a type of non-volatile random-access memory.PRAMs exploit the unique behaviour of chalcogenide glass.his burst of voltage is provided by a charge pump, which takes some time to build up power. General write times for common Flash devices are on the order of 0.1ms (for a block of data), about 10,000 times the typical 10 ns read time, for SRAM for example (for a byte).
Bias voltage is the amount of voltage that an electronic device needs in order to power on and function. Without bias voltage, an electronic device wouldn't have the power to turn on and be operated. A microphone is one such device which needs bias voltage in order to operate. If a microphone doesn't receive this power, it can't record any signals and thus it's inoperable.
