Memory device with programmable control for activation of read amplifiers

A system, comprising:

• a controller;
• and
• a memory device coupled to the controller, the memory device including:
• a dummy memory structure including a plurality of dummy memory cells each coupled to a respective decode signal line via a respective access transistor, at least one dummy bit line and a dummy word line, the dummy memory structure operable to discharge a current through the at least one dummy bit line in a selected time, the selected time a function of the number of the dummy memory cells that are programmed;
• a memory controller coupled to the dummy memory structure and operable to output a read activation signal responsive to the current;
• and
• a memory cell array including a plurality of memory cells, the memory cell array coupled to the memory controller to receive the read activation signal.

A method, comprising:

• generating a decode signal;
• programming a selected first number of dummy memory cells from among a plurality of dummy memory cells with the decode signal to set a first discharge time for discharging at least one dummy bit line;
• and
• discharging at least one dummy bit line coupled to the plurality of dummy memory cells in the first discharge time.
