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).
An ideal voltmeter has two terminals and senses the voltage between the terminals where they may be connected to a circuit. Ideally the voltmeter has infinite resistance. It is polarized and indicates polarity as well as the magnitude of the voltage. An ideal ammeter is a two terminal device, also polarized. It is connected in series with circuit elements to measure the sign and magnitude of the current flowing through that component. The circuit has to be opened to insert the ammeter to measure current flow. The ideal ammeter has no resistance to flow.
