what is Probe Map - a map showing where the test vias are located on a DIMM and the associated timing skew offset that has been calculated to account for the timing difference between the probe point measurement location and the location of where the signal is to be verified (ie: the ball location under the DRAM BGA on a DIMM)

RAMpedia is a DRAM memory encyclopedia and reference tool
