Distributed memory

Definition

Distributed memory refers to a memory architecture in which data is stored across multiple locations, allowing for parallel access and processing. This setup enables neuromorphic systems to mimic the way biological brains operate by spreading information processing across various nodes, enhancing efficiency and scalability.

5 Must Know Facts For Your Next Test
