VG4616322B Datasheet | Vanguard International Semiconductor

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 mand which is then followed by a Read or...
