摘要
Recently, the market for mobile multimedia products has been growing- Law power is important for making these products more portable, allowing extended use with small, lightweight batteries. Flash memories are well-suited as a storage medium for these products because of their nonvolatility and compactness, and their market is rapidly growing. The line up of the SuperH RISC engine series (SH-1, SH-2, SH2-DSP, SH-3, SH3-DSP, and SH-4) offers low-power products in a wide range of performance levels. The series covers all of the needs of mobile multimedia products because it integrates peripheral circuits, memories, and other devices, to reduce overall system cost. We released the ×64-type 256-Mbit SDRAM for the main memory in 1999. Its multichip packaging gives it high capacity and high speed in a small mounting area. Infineon Technologies and Hitachi jointly released the 16-Mbyte flash card, called the MultiMediaCard, which so far is the smallest and lightest currently available. Combined with Hitachi's original AND type cell, this flash memory offers a high capacity and low cost.
