200 Each UMC contains eight channels. Each UMC channel controls one 128-bit
202 of 4096-bits of DRAM data bus.
209 GPU DF / GPU Node -> EDAC MC
210 GPU UMC -> EDAC CSROW
211 GPU UMC channel -> EDAC CHANNEL
218 - The CPU UMC (Unified Memory Controller) is mostly the same as the GPU UMC.
219 They have chip selects (csrows) and channels. However, the layouts are different
221 - CPU UMCs use 1 channel, In this case UMC = EDAC channel. This follows the
223 - CPU UMCs use up to 4 chip selects, So UMC chip select = EDAC CSROW.
224 - GPU UMCs use 1 chip select, So UMC = EDAC CSROW.
225 - GPU UMCs use 8 channels, So UMC channel = EDAC channel.
