The AT45DB081E-SHN-B is a 1.7V minimum, serial-interface sequential access Flash Memory ideally suited for a wide variety of digital voice, image, program code and data storage applications. This also supports the RapidS serial interface for applications requiring very high speed operation. Its 8650752-bit of memory are organized as 4096 pages of 256 or 264 bytes each. In addition to the main memory, the memory also contains two SRAM buffers of 256/264 bytes each. The buffers allow receiving of data while a page in the main memory is being reprogrammed. Interleaving between both buffers can dramatically increase a systems ability to write a continuous data stream. In addition the SRAM buffers can be used as additional system scratch pad memory and E2 PROM emulation (-bit or byte alterability) can be easily handled with a self-contained three step read-modify-write operation.
Continuous read capability through entire array
