NEC Corp on Tuesday announced that is has begun sample shipments of five types of 3.3V 16M-bit synchronous dynamic RAMs synchronous devices run from an internal clock – and the come in clock speeds of 33MHz, 66MHz and 100MHz for high-speed transfer of data. The products are known as uPD4516421, 4M by 4 bits, to 1m by 18 bits. Monthly production will start at 30,000 units in June rising to 300,000 units in December this year. NEC says that its synchronous dynamics operate faster than conventional DRAMs, transferring data at up to 800M-bytes per second in a 64-bit system – and can take advantage of very high clock rates and improve overall system performance. They will increasingly find a place in high-end applications and gradually increase their market share over conventional DRAMs, according to NEC. The company plans to offer sample quantities of the 33MHz version in a 4M by 4 organisation for approximately $180 each, in a 2M by 8 or 1M by 16 organisation for about $210 each, and in a 2M by 9 or 1M by 18 organisation for some $220 each. The US subsidiary announced the parts at the same time.
