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. The output of another selected individual memory component identified by the n lower order bits of the current address is enabled without generating wait states, if the current and preceding addresses identify a same page. The process of providing consecutive subsequent addr…
