Description
The V826516K04S memory module is organized
16,777,216 x 64 bits in a 184 pin memory module.
The 16M x 64 memory module uses 8 Mosel-Vitelic
16M x 8 DDR SDRAM. The x64 modules are ideal
for use in high performance computer systems
where increased memory density and fast access
times are required.

Notes: 1. VID is the magnitude of the difference between the input level on CK and the input on CK.
2. The value of VIX is expected to equal 0.5*VDDQ of the transmitting device and must track variations in the DC level of the
same.
