Sunnyvale, Calif. - Fujitsu Microelectronics America Inc.'s MB84SR6H5K5K1 multichip package combines fast-cycle RAM and burst-mode flash memory chips for use in next-generation mobile phones. The package includes one 128-Mbit NOR-type flash memory and two 64-Mbit mobile FCRAMs capable of burst-mode operation at 66 MHz, enabling high-speed data access, Fujitsu said. Burst-mode access time is 11 nanoseconds for flash, 12 ns for mobile FCRAM (at 66 MHz). Operating on 1.8-V power, the flash memory requires a maximum of 10 microamps, the mobile FCRAM a maximum of 120 microamps of standby current. Operating voltage range is 1.65 to 1.95 V; operating temperature range is -30 degrees C to 85 degrees C. In a 115-pin FBGA configuration, the MB84SR6H5K5K1 sells for $50 in small sampling quantities.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
