PCI / ISA desktop personal computer systems based on 64-bit Slot-A (AMD K7) processors. The K7VA133 supports three banks of SDRAMs up to 256MB. The SDRAM controller supports standard either Synchronous DRAM(SDRAM) or Virtual Channel Memory (VCM), in a flexible mix/match manner. The Synchronous DRAM interface allows zero wait state bursting between the SDRAM and the data buffers at 100 MHz.
