 EEPROMs, however, are still used on applications that only require small amounts of storage, like in serial presence detect.Flash memory packages can use Die stacking with through-silicon vias and several dozen layers of 3D TLC NAND cells simultaneuosly to achieve capacities of up to 1 terabyte per package, with an integrated flash controller.The origins of flash memory can be traced back to the development of the floating-gate MOSFET (FGMOS), also known as the floating-gate transistor.
