Well, what about RAM, PC and so on? They might be an extreme example but if you are in the 'field' not using abbreviations may actually bug you more. Targeting audience is not an easy task.
Didn't have to google RAM, PC and so on.
It is often better to use “computer” and “memory”, especially when the distinction between L1/L2/L3/RAM/SSD/HDD is not the main topic.
