Elpida Completes Development of New 50nm Process 2-Gigabit Mobile RAM

By Nathan Kirsch

Elpida Memory announced late yesterday that they had completed development of a 50nm process 2-gigabit Mobile RAM product using 50nm process technology with 193nm (ArF) immersion lithography and copper interconnect. 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. This is important as it will remove the delay found when doing video playback on smart phones like the Blackberry Bold. The Blackberry Bold plays movies fine, but good luck skipping a scene.

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. Thus it can meet demand for high-resolution high-quality graphics display and high bandwidth video play.
