Abstract

A synchronous flash memory has been described that includes an array of non-volatile memory cells. The memory device has a package configuration that is compatible with an SDRAM. The synchronous flash memory device includes an array of non-volatile memory cells arranged in a plurality of rows and columns. During a read operation, a row of the memory array can be accessed and data read from a group of columns during a burst operation. The burst columns are generated using an internal counter and an externally provided start address. The memory generates the burst column addresses by modifying the least significant column address signals only. For a burst length of two, only the least significant address bit is modified. For a burst length of four, only the two least significant address bits are modified. Finally, only the three least significant address bit s are modified for a burst length of two. In one embodiment, the burst addresses rotate through the defined column group in a cyclical manner.
