VME64 is an expanded version that provides 64-bit data transfer and addressing. The VMEbus supports a 24-bit address and 16-bit data transfers using only the upper (J1) backplane. The bus supports a 32-bit address and 32-bit data transfers by adding the lower (J2) backplane. Most VMEbus systems were originally built with separate J1 and J2 backplanes. As VMEbus systems increased in performance, monolithic J1/J2 backplanes were developed to reduce backplane bus noise.
