V55C2256164VB 256Mbit MOBILE SDRAM 2.5 VOLT FBGA PACKAGE 16M X 16 is a high performance mobile SDRAM in the V55 series. It supports up to 143MHz clock speed and has a four-channel, 4Mbit x 16 organization.
The ProMOS V55C2256164VB is a four-bank synchronous DRAM organized as 4 banks x 4Mbit x 16. It achieves high-speed data transfer rates up to 143 MHz by employing a chip architecture that prefetches multiple bits and synchronizes output data to a system clock. All control, address, data input, and output circuits are synchronized with the positive edge of an externally supplied clock.
