There are two VRAM chips on the SNES motherboard, both connected to S-PPU1. They are both SRAM and each 32K x 8 bit (32,768 bytes) in size, for a total of 65,536 bytes.
One chip holds the low bytes of the 16-bit words, the other chip holds the high bytes.
The two chips can be referred to as "A" and "B", after the lines of the VRAM Data Bus VDA0~7 and VDB0~7.
