Abstract
Flash-type memory access and control is facilitated (e.g., as random-access memory). According to an example embodiment, an interface communicates with and controls a flash memory circuit over a peripheral interface bus. The interface uses a FIFO buffer coupled to receive data from and store data for the flash memory circuit and to provide access to the stored data. An interface controller communicates with the flash memory circuit via the peripheral interface bus to initialize the flash memory circuit and to access data thereto, in response to requests from a processor. In some applications, the flash memory circuit is initialized by sending commands to it. The interface may be placed into a read-only mode in which data in the flash memory is accessed as part of main (computer) processor memory, using the FIFO to buffer data from the flash.
