What is Bank?
One of several independently operating sections inside a DRAM. Overlapping activation and access across different banks raises effective performance.
Field: DRAM
Bank in the explanations
During refresh, the bank cannot be accessed and power is consumed, a burden that grows with capacity.
Why does DRAM need periodic refresh operations?Dividing the DRAM into banks lets one bank be accessed while another performs these operations, hiding the latency and improving throughput.
What is the main purpose of dividing the inside of a DRAM i…Mitigations include per-bank refresh, which keeps other banks available, and research into refreshing long-retention rows less often.
As DRAM capacity grows, what tends to become a problem with…
