INTELLIGENT CHARGE PUMP ARCHITECTURE FOR FLASH ARRAY

Abstract:

The present disclosure relates to a non-volatile memory device and to a method for generating overvoltage values in such a memory device structured in a plurality of sub-arrays and including: at least a decoding and sensing circuitry associated with each sub-array; a charge pump architecture for each sub-array including pump stages for increasing the value of an input voltage and obtaining an overvoltage output value; a control and JTAG interface in said memory device; at least a registers block coupled to said charge pump architecture and driven by a logic circuit portion for receiving at least an activation signal selecting a specific charge pump architecture associated with a memory sub-array of the plurality of sub-arrays.
