Abstract
Data bus capacitance is reduced by decoupling unaccessed memory circuits from a data bus during data transfers to or from other memory circuits.
Claims12
A method of making a memory module comprising:
- attaching at least one memory integrated circuit to a printed circuit board, said printed circuit board comprising data bus contacts on a portion thereof;
- and
- coupling said data bus contacts on said printed circuit board to data bus terminals on said memory integrated circuit through a bus switch on said printed circuit board.
A method of making a memory module comprising:
- attaching at least one memory integrated circuit to a printed circuit board, said printed circuit board comprising data bus contacts on a portion thereof;
- and
- coupling said data bus contacts on said printed circuit board to data bus terminals on said memory integrated circuit;
- and
- positioning a switch in a data path to the memory integrated circuit
2 more elements
A method of making a memory integrated circuit comprising the acts of:
- connecting data input terminals to an input portion of a bus switch;
- connecting an output portion of said bus switch to a data input buffer;
- and
- coupling an output of said data input buffer to a memory storage circuit.
1 more element
A method of data transfer across a bus comprising the acts of:
- reducing the parasitic capacitance of said bus by isolating at least a first segment of said bus;
- and
- utilizing a second segment of said bus for data transfer.
