SAN JOSE, Calif. -- Fujitsu Ltd. has introduced a multi-chip package (MCP) for mobile telephone applications that includes three flash memories, one static SRAM, and two fast cycle RAM die. However, the sample price for the multi-format memory is $65; more than many people expect to pay for a complete cellular telephone.
Fujitsu's device bonds a pair of packages into a single unit that has dual bus structure so that data and program memory spaces can be addressed simultaneously.
"This high-density MCP is a breakthrough product for the new generation of full-function cellular technology," said Keith Horn, vice president of marketing for Fujitsu Microelectronics America Inc., in a statement. "As cellular phones incorporate video capture, Internet access and other exciting new features, they require significantly more memory in very dense packages."
The MB84VY6A4A1 measures 15-mm by 11-mm, with a height of 1.4 mm. Ball pitch is 0.8-mm. It is the same size as Fujitsu's four-chipMCP but memory capacity is increased by approximately 20% in the new six-chip version.
The upper part of the package includes 128-Mbit and 64-Mbit NOR-type flash memories, and 64-Mbit and 32-Mbit mobile FCRAMs. The lower section includes a 32-Mbit NOR-type flash and an 8-Mbit SRAM.
The multi-format memory component comes in a standard plastic 179-pin ball grid array. Sample prices start at $65 each and devices will be available by the end of November, Fujitsu said.
