Combination field programmable gate array allowing dynamic reprogrammability
Abstract
A cell that can be used as a dynamic memory cell for storing data used in programming a field programmable gate array (FPGA) is disclosed. The cell comprises a select transistor having a gate, a source, and a drain, the gate connected to said write bitline, the source connected to a floating point node, and the drain connected to a row wordline. A sense device determines the data stored on the floating point node. Finally, switch that is controlled by the floating point node is provided.
