Reactive placement controller for interfacing with banked memory storage

A method for placing commands within a queue of a placement controller, comprising the operations of:

• receiving a new inbound command for a banked memory device, the new inbound command having an associated priority value and a command type;
• determining whether a priority bracket exists for the priority value of the new inbound command;
• when a priority bracket exists for the priority value, determining whether a read/write bracket exists within the priority bracket for the command type of the new inbound command;
• and
• when a read/write bracket exists for the command type, determining whether the new inbound command addresses a different page in a memory bank addressed by a command in an adjacent queue entry.

A reactive placement controller for interfacing with a banked memory storage, comprising:

• a read/write module coupled to a command control module for a banked memory device;
• and
• a command queue including a plurality of queue entries coupled in series, the plurality of queue entries including a top queue entry coupled to the read/write module, each queue entry capable of storing a memory command,
• wherein each queue entry is coupled to a plurality of priority chains, each priority chain including a plurality of AND gates in a chain, the priority chains capable of allowing higher priority queue entries to disable lower priority queue entries.
