WebThe DDR4 SDRAM uses a 8n prefetch architecture to achieve high-speed operation. The 8n prefetch architecture is combined with an interface designed to transfer two data words per clock cycle at the I/O pins. A single read or write operation for the DDR4 SDRAM consists of a single 8n-bit wide, four clock data transfer at the internal DRAM core ... WebMay 2, 2024 · There are two types of latency to consider when looking at the cycle by cycle transmission of data on the DDR4 Data Bus. The first is the time between the Read or Write command and the data associated with that command, refered to as CAS and CAS Write latency, and then there is the time between successive Read/Write Commands.

WebJun 12, 2024 · Each of the four RAM timing numbers represents a different variable. Let’s start with the first: tCL (CAS Latency): This refers to the delay (latency) between your CPU requesting data from the RAM and the time that the RAM starts sending it. The lower the CAS latency, the less delay. WebDec 22, 2024 · As latency is the delay that occurs between operations, it can have a serious impact on the performance of RAM if it increases beyond a certain limit. The timings of the RAM are a depiction of the inherent latency that can be experienced by the RAM while performing its various operations. RAM timing is measured in clock cycles.
