Detailed Description

A basic class to track the bank state, i.e.

what row is currently open (if any), when is the bank free to accept a new column (read/write) command, when can it be precharged, and when can it be activated.

The bank also keeps track of how many bytes have been accessed in the open row since it was opened.
