Morphology
The meaning 'a particularly important or central memory' is directly derivable from combining 'core' (central/essential) with 'memory' (a recollection). This is a straightforward compositional/metaphorical extension that a B1 learner who knows the basic senses of the constituents would readily infer, though learners who only know a very technical sense of 'core' (e.g., a ferrite ring) might be briefly puzzled.
Etymology
Core memory comes from early computers that used tiny magnetic rings called cores. Each ring could hold information even when the 'power' was off, so the picture of small rings holding data helps explain why the term means a strong, long-lasting kind of computer memory.
