CAS Latency?
- mat_epice 3y agoIndeed, it probably has one.
- mips_r4300i 3y agoDRAM itself hasn't really changed too much for decades, and the length of time for the cas latency is determined by physics, so it's probably comparable to any other dram. Once you have the row open though, you can burst it out almost instantly over the very wide bus HBM gives you.
- borlanco 3y agoThis paper has lots of info about HBM. They explain CAS latency in page 4: "Demystifying the Characteristics of High Bandwidth Memory for Real-Time Systems" https://upcommons.upc.edu/bitstream/handle/2117/362010/HBM.pdf https://upcommons.upc.edu/bitstream/handle/2117/362010/HBM.p... > For this CAS latency, HBM (Observation 6) offers a significant advantage over regular DRAMs. This is because HBM has tCCD = 1 or 2 compared to tCCD >= 4 for DRAM. Accordingly, HBM can reduce the CAS latency component to at least half of its DRAM value.
