o why is memory considered an active reconstructive process
Reconstructive memory Memory is never a literal recount of past experiences. Rather, it is dependent on the constructive processes present at the time of encoding that are subject to potential errors and distortions. Essentially, the constructive memory process functions by encoding the patterns of physical characteristics that are perceived by the individual, as well as the interpretive conceptual and semantic functions that act in response to the incoming information.[1] By utilizing multiple interdependent cognitive processes there is never a single location in the brain where a given complete memory trace of an experience is stored.[2] In this manner, the various features of the experience must be joined together to form a coherent representation of the episode and if this binding process fails it can result in source memory failure, where later attempted retrieval of the episode results in fragmented recollection and an inability to consolidate the information into a cohesive narrative of a past experience. During the recall of Episodic memory, the information that a person remembers is usually limited in scope, ultimately giving an incomplete recollection of an event. By employing reconstructive processes, individuals supplement other aspects of available personal knowledge into the gaps found in episodic memory in order to provide a fuller and more coherent version, albeit one that is often distorted.
Static random-access memory The term static differentiates SRAM from DRAM (dynamic random-access memory) which must be periodically refreshed. SRAM is faster and more expensive than DRAM; it is typically used for CPU cache while DRAM is used for a computer's main memory.
