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.

Abstract: A flash memory chip that can be switched into four different read modes is described. In the first read mode, asynchronous flash mode, the flash memory is read as a standard flash memory where the reading of the contents of a first address must be completed before a second address to be read can be specified. In the second read mode, 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 tick. Then, the contents stored at the addresses specified for the burst are output sequentially during subsequent clock ticks in the order in which the addresses were provided. Alternately, if a single address is provided to the flash chip when it is in the synchronous mode, the subsequent addresses for the burst will be generated within the flash chip and the data burst will then be provided as output from the flash chip.

Abstract: An asynchronous nonvolatile memory includes a plurality of individual memory components. A burst read operation references consecutive addresses beginning with a first address, wherein the consecutive addresses are not located in a same memory component. A method of performing a burst read operation in the asynchronous nonvolatile memory includes the step of providing the first address as a current address to the plurality of individual components. A current page identified by m higher order bits of the current address is selected. Each of the individual memory components senses a location identified by the m higher order bits. An output of a selected individual memory component is enabled in accordance with n lower bits of the current address. A consecutive subsequent address is provided, wherein the current address becomes a preceding address and the consecutive subsequent address becomes the current address.
