1. A memory system comprising:

  • a buffer memory section;

    a non-volatile memory section connectable to the buffer memory section, including a first array of non-volatile memory cells arranged into a NAND type of architecture, including a plurality NAND strings and a plurality word lines spanning the NAND strings, each of the word lines connected to a corresponding one of the memory cells thereof, wherein the first array is written as pages of data along selected word lines; and

    control circuitry connected to the buffer memory section and the non-volatile memory section, wherein the control circuitry can;

    store data keys received from a host to which the memory circuit is connected in the buffer memory;

    subsequently form the data keys stored in the buffer memory into pages of data such that when written into the non-volatile memory section, the data keys are oriented along NAND strings of the first array; and

    transfer the data pages to the non-volatile memory section to be written into the first array.
