A memory system or flash card may include a controller interface for communicating with a host. The interface utilizes multiple pre-driver logic blocks that are tolerant to different voltages. For example, one block may use gate oxide devices tolerant to IO low voltage that speed up the delay path during low voltage operation, while a second block may use gate oxide devices tolerant to IO higher voltage for backwards compatibility with devices that operate at a high IO voltage. This allows the interface to take advantage of the IO low voltage device speed for multi-purpose IO use, while still being used for both low voltage and higher voltage protocols.
