Fujitsu Sampling 64 MB FCRAM With Double Data Rate SDRAM Interface.Fujitsu Limited and Fujitsu Microelectronics Europe GmbH (FME FME Formal Methods Europe FME Faculty of Mechanical Engineering (Brno University of Technology, Czech Republic) FME Feature Manipulation Engine FME Facultat de Matemà tiques I EstadÃstica ) last week introduced samples of the company's new 64 Megabit Fast Cycle RAM (FCRAM FCRAM Fast Cycle Random Access Memory FCRAM Fast Cycle Ram ) with Double Data Rate (DDR) SDRAM (Synchronous DRAM) A type of dynamic RAM (DRAM) memory chip that has been widely used since the late 1990s. SDRAM chips eliminated wait states by dividing the chip into two cell blocks and interleaving data between them. interface. Designed for graphics, multimedia and automotive applications, the FCRAM features high speeds and low power consumption. The 64 MB FCRAM with DDR interface is the first in a series of Application Specific Memory (ASM) products based on the FCRAM architecture, which was introduced in June 1998 at the VLSI VLSI: see integrated circuit. (1) (Very Large Scale Integration) Between 100,000 and one million transistors on a chip. See SSI, MSI, LSI and ULSI. (2) (VLSI Technology, Inc., Tempe, AZ, www.semiconductors. Symposium as Fujitsu's next generation of high-speed memory technology. The new ASMs feature a 200 MHz clock speed, DLL controlled output, and a 400 Megabit/second/pin data transfer rate. All versions use page mode operation. Random access speeds are very high, with the fastest random cycle time measured at 30 nanoseconds. |
