Elpida Memory today announced<
The ultra low-power features of Mobile RAM are ideal for use in mobile phones, portable multimedia devices, portable internet-related devices and other handheld device applications. In its development of Mobile RAM Elpida has focused on conserving electric current. Compared with 70nm products the new 50nm product uses less than half the data retention current and half the operating current. These enhanced features enable double the memory capacity without an increase in system power consumption.
The new product optimizes the pad layout for PoP (Package on Package), MCP (Multi Chip Package) and other packaging technology and is designed to meet the need for smaller yet higher capacity memory packages for use in mobile devices.
It uses an x32-bit I/O configuration based on double-data rate (DDR) that can operate at an extremely fast speed of 400Mbps (200MHz) to transmit data at the rate of 1.6 gigabytes per second. In addition to JEDEC standard 1.8V the product supports 1.2V supply voltage to further lower power consumption.
Elpida's newest Mobile RAM supports both single-data rate (SDR) and the more advanced DDR and has either an x32 bit or x16 bit I/O configuration on a single-chip.
The company plans to begin mass production of this product in the first half of CY 2009.
