Direct memory access interface in integrated circuits

A direct memory access system comprising:

• a memory device containing one or more memory cells;
• at least one memory bit line in electrical communication with at least one of said memory cells;
• a measurement device;
• a data source capable of producing selection data;
• a measurement control device configured to produce an access enable signal;
• and
• at least one register element electrically coupled to said at least one memory bit line, said at least one register element each comprising:
• a memory access gate coupled to said memory bit line, a memory access line coupled to said memory access gate and said measurement device, a bidirectional data line coupled to said data source, a storage element coupled to said bidirectional data line and said measurement control device, and a memory access select gate coupled to said memory access gate, said storage element, and said measurement control device.

A method for controlling direct memory access, the method comprising:

• selecting a memory cell in a memory array;
• writing a selection bit to a storage element, said storage element associated with said selected memory cell;
• generating a select signal from said storage element containing said selection bit;
• receiving said select signal at a selection gate to allow access to said selected memory cell, said access providing electrical communication with said memory cell;
• and
• coupling said selected memory cell to an access line, said access line allowing electrical equipment to be coupled to said selected memory cell allowing characterizing of said memory cell.
