CONFIGURABLE AND REUSABLE NAND SYSTEM

摘要

A configurable and reusable hardware-software NAND system adaptive to various NAND devices independent of the NAND device manufacturer and NAND device characteristics. A device identification signature is decoded from a NAND device in a NAND system; the device identification signature signal is analyzed to obtain a control phase sequence value descriptive of a characteristic of the NAND device; the control phase register is populated with the control phase sequence value; and control phase register provides the control phase sequence values to the command sequencer. The control phase register can be programmed by a low level driver for devices which NAND system cannot decode the device identification signature.
