Cypress Semiconductor launched dual-port RAMs targeted at mobile-phone and PDA applications, such as the More Battery Life (MoBL) name tag. The devices are aimed at enabling high-speed interprocessor communication in next-generation phones that use multiple processors to handle video, games, e-mail or music. At 1.8V, operating current is only 15mA and standby current is just 2µA (typical), extending both talk and standby times in mobile phones. Designed with two independent SRAM interfaces, the MoBL dual-port memory chips enable processors to efficiently exchange data, letting communication and application subsystems evolve independent of each other. The chips support 1.8, 2.5 and 3V I/O voltages, with densities up to 256Kb. They deliver access times as fast as 35ns and data rates of over 200Mbps per port to avoid data-flow bottlenecks. An 8-bit bus-width option reduces trace route and simplifies board layout. The MoBL Dual-Ports are offered in a 100-ball, 0.5mm-pitch, 6x6mm fpBGA package. They come in 16Kx16, 8Kx16, 16Kx8, 4Kx16 and 8Kx8 configurations.
