Patent ID: 7675802

Claim:
A nonvolatile memory card that interfaces with a host comprising: an array of nonvolatile memory cells on a first die; a memory controller that manages data in the array of nonvolatile memory cells, the memory controller on a second die; a single voltage regulation die located on the nonvolatile memory card and including a voltage regulation circuit located on the nonvolatile memory card and that is capable of receiving plural distinct input voltage levels in the group of 1.8V, 3.3V, and between 3.3V and 3.6V from the host and regardless of which one of the plural distinct input voltage levels in the group is supplied by the host, for supplying the same output voltage level of 3.3V to the second die, the voltage regulation circuit receiving an input voltage from the host, the voltage regulation circuit providing an output voltage at a first level equal to the input voltage when the input voltage is at the first level, and the voltage regulation circuit also providing the output voltage at the first level when the input voltage is at a second level, the output voltage of the voltage regulation circuit provided to the first die; wherein the voltage regulation circuit is switched to operate as a charge pump when the input voltage is 1.8V and as a voltage follower when the input voltage is 3.3V; wherein the voltage regulation die is stacked on the second die; and wherein the first die comprises a single power supply voltage level memory die.
