Introduction to DRAM (Dynamic Random-Access Memory)

WebApr 2, 2024 · DRAM stands for “dynamic random access memory,” and it’s a specific type of RAM (random access memory). All computers have RAM, and DRAM is one kind of RAM we see in modern desktops and laptops. DRAM was invented in 1968 by Robert Dennard and put to market by Intel® in the ‘70s. WebMay 26, 2011 · DRAM CAS Write Latency: Also known as CWL. Sets the column write latency timing for write operations to DRAM. For most purposes the minimum value should be equal to read CAS, as the timing constraints of accessing a column are the same. This timing is just as important as read CAS because data has to be written to DIMMs in order …
