Systems and/or methods that facilitate high performance flash channel interface techniques are presented. Integrated error correction code (ECC) engine and buffer sets facilitate bypassing error correction of data being written to or read from memory, such as flash memory, in addition to single ECC mode or multiple ECC mode. The integrated ECC engines and buffers can quickly analyze data, and provide error correction information or correct error, significantly increasing throughput. In addition, the programmable flash channel interface can provide more rapid development of flash products by accommodating both Open NAND Flash Interface (ONFI) standard flash and legacy flash devices, by using a configurable micro-code engine in the flash interface.

High performance flash channel interface

A system and method are provided for periodically servicing a channel in a timer used for controlling events. The method services a channel in a fixed periodic cycle, and reads a first control word loaded in the channel to determine a timer operation. Then, a first data word in the channel is managed in response to the determined operation. In one aspect, a clock signal is supplied with a fixed period. Then, servicing the channel in a fixed periodic cycle includes: establishing a cycle having a first number of clock signals; and, servicing the channel for a second number of clock signals each cycle. If the timer includes a plurality of channels, then each channel is serially serviced in a single cycle.
