Scalable Embedded DRAM Array

A method and apparatus for scaling an embedded DRAM array from a first process to a second process, wherein the scaling involves reducing the linear dimensions of features by a constant scale factor. From the first process to the second process, DRAM cell capacitor layout area is reduced by the square of the scale factor, while cell capacitance is reduced by the scale factor. The voltage used to supply the logic transistors is scaled down from the first process to the second process. However, the voltage used to supply the sense amplifiers remains constant in both processes. Thus, in an embedded DRAM array of the second process, sense amplifiers are supplied by a greater voltage than the logic transistors. This allows the sensing voltage of DRAM cells to be maintained from one process generation to another, while allowing memory size to scale with the square of the process scale factor.
