I have never heard of a NAND with 4K erase units (unless these were the very
old 256-byte page devices).
Most have programming pages used today are 512+16 or 2k+64 byte pages with
erase sizes of 16k and 128K respectively.

I suggest you read the Toshiba NAND flash appliocation guide. it will tell you
almost everything you need to know.
