Flash memory is an electrically erasable and programmable permanent type of memory. It uses a one-transistor memory to store a bit. It offers low power consumption and helps to reduce the cost. It is mainly used in digital cameras, MP3 players, etc. The only difference between the two is that it has a higher bandwidth, which offers greater speed. Skip to content.

They react to changes as the control inputs change, and also they are only able to operate as the requests are presented to them, dealing with one at a time.

SDRAM is able to operate more efficiently. It is synchronised to the clock of the processor and hence to the bus. With SDRAM having a synchronous interface, it has an internal finite state machine that pipelines incoming instructions. This enables it to operate at much higher speeds. By transferring data alternately from one set of addresses, and then the other, SDRAM cuts down on the delays associated with asynchronous RAM, which must close one address bank before opening the next.

The term pipelining is used to describe the process whereby the SDRAM can accept a new instruction before it has finished processing he previous one. In other words, it can effectively process two instructions at once. For writing, one write command can be immediately followed by another without waiting for the original data to be stored within the SDRAM memory itself. For reading the requested data appears a fixed number of clock pulses after the read instruction was presented.

It is possible to send additional instructions during the delay period which is termed the latency of the SDRAM.
