Cache memory storage amount and size of the cache memory device is same.

Question

Question restatement: The statement says 'Cache memory storage amount and size of the cache memory device is same.' Options: True, False.
Option 1: True. This claim asserts that the storage amount and the size of the cache memory device are identical. In practice, this is not accurate because the term 'storage amount' refers to how much data the cache can temporarily hold, while 'size of the cache memory device' refers to the physical or nominal capacity of the cache hardware itself. These two concepts are related but not necessarily equal, as cache design can involve effective usable space that differs from nominal hardware size due to architecture, associativity, and reserved areas. Therefore, labeling them as the same is misleading and generally incorrect.
Option 2: False. This option correctly indicates that the storage capacity available for caching data and the physical size or declared capacity of the cache hardware are not inherently the same quantity. The cache’s effective storage (how much data it can store at once) can be influenced by architectural decisions (like cache lines, associativity, and tagging) and may not coincide with the raw hardware size or the device’s rated capacity. In short, there is no automatic equivalence between 'storage amount' and 'cache device size,' making this statement false.
Note on potential misconceptions: Some learners might conflate 'size' with 'amount of data cached at runtime' or think that the cache always uses all its physical capacity. In reality, cache utilization depends on workload, cache organization, and hit/miss behavior, so the two terms do not have to match. Additionally, different levels of cache (L1, L2, L3) have different sizes and effective storage characteristics, adding to the distinction between hardware size and cache storage capacity.
Overall takeaway: The correct characterization is that cache storage capacity and cache device size are not necessarily the same thing, so the statement provided is not accurate.

Cache memory storage amount and size of the cache memory device is same.
