A method and apparatus are provided for programming a non-volatile data storage device, in which a fast write operation can be performed using a plurality of page buffers included in the non-volatile data storage device when the write operation is performed in a way of using interleaving for each channel in a multi-channel system using a plurality of non-volatile data storage devices. The method includes programming data in a memory cell array included in the non-volatile data storage device using a page buffer selected from among a plurality of page buffers included in the non-volatile data storage device and performing a setup operation for loading data using another page buffer, which is different from the page buffer selected during the programming.

Method and apparatus for programming non-volatile data storage device

The present invention relates to a bridge for interfacing buses within an embedded system. There is provided a method of interfacing a first bus and a second bus operating at different speeds, the method includes counting a match value assigned to a predetermined peripheral device among peripheral devices connected to the second bus for each cycle of a clock signal received from the first bus, and keeping a read state or a write state for the predetermined peripheral device by continuously outputting a read signal or a write signal for the predetermined peripheral device to the second bus, during the counting of the match value. According to the present invention, it is not necessary to operate depending on a peripheral device operating at the lowest speed among peripheral devices, and not necessary to add wrappers to the peripheral devices, by employing the AHB-to-ISA bridge variably adjusting the output times of output signals to an ISA bus.
