A 128 Mb NOR flash memory with 3 MB/s program time and low-power write performance by using in-package inductor charge-pump

Improved performance of flash memories requires programming more cells in parallel. This design uses an inductive pump to transfer the energy to a capacitor to achieve the needed voltage. The discrete inductor is bonded atop the die which also includes the control circuitry. With an inductive pump, the current saving in the program mode is 47.5 mA compared to a capacitive pump.
