Abstract
A method for reading a first data bit from a non-volatile memory of a memory system is disclosed. The N most-significant bits are stored for each of M words in a rotated storage section. Address bits are serially received according to the clock signals. Before receiving a final address bit, a rotated word made up of the most significant bit of the M words is fetched from the rotated storage section. Address bits are serially received and rotated words are fetched until the N most-significant bits of the M words have been fetched. Then, un-rotated words are serially fetched from the non-volatile memory. Within one clock signal of the final address bit receipt, a bit is selected out of the fetched rotated words based on the received address bits. The first data bit is returned based on the selected bit and un-rotated words are returned based on the address.
