Review Zone heeft een RAM guide in elkaar gefixed. Het is best wel goede info voor het geval je niet helemaal up-to-date bent op RAM gebied. Hier wat soep over latency timing:
It’s easy to visualise DRAM in terms of a spreadsheet: cells, rows, columns, the works. Bits of information are stored in rows and columns. The speed at which you access a single row of RAM is called Row Access Strobe Latency (RAS Latency) while the speed at which you access a single column of RAM is similarly called Column Access Strobe Latency (CAS Latency). Obviously, the lower the rating, the better. CAS Latency ratings differ between chips, but that doesn’t mean it’s a hardwired feature. It varies depending on the bus speed you’re using: that is, a chip with a CAS-2 rating at a 66MHz bus speed may have to go at CAS-3 if used at a 100MHz bus speed lest you experience instability.
