VIS Overview Preliminary VG4616321B/VG4616322B 262,144x32x2-Bit CMOS Synchronous Graphic RAM The VG4616321(2) SGRAM is a high-speed CMOS synchronous graphics RAM containing 16M bits.
It is internally configured as a dual 256K x 32 DRAM with a synchronous interface (all signals are registered on the positive edge of the clock signal, CLK).
Each of the 256K x 32 bit banks is organized as 1024 rows by 256 columns by 32 bits.
Read and write accesses to the SGRAM are burst oriented; accesses start at a selected location and continue for a programmed number of locations in a programmed sequence.
Accesses begin with the registration of a BankActivate command which is then followed by a Read or W...
