Abstract
A flash memory chip that can be switched into four different read modes is described. In asynchronous flash mode, the flash memory is read as a standard flash memory. In synchronous flash mode, a clock signal is provided to the flash chip and a series of addresses belonging to a data burst are specified, one address per clock period. The data stored at the specified addresses are output sequentially during subsequent clock periods. In asynchronous DRAM mode, the flash memory emulates DRAM. In synchronous DRAM mode, the flash memory emulates synchronous DRAM.
