    Hi folks

    I am new to Semiconductors. Pardon my ignorance if my doubt seems silly.

    How much time it takes to transfer 1 MB (512K x 2) of data from a non-volatile memory( of access time 5 ns) to a DRAM.

    Thanks.

    Depends upon the word length of the bus and the bus speed.

    Can you please make an assumption on word length, bus speed, do the calculations and show how its done.

    Thanks

    If you assume a bus width of 8-bit (one byte) and a 10MHz bus speed, then it would take 1MB / 10MHz = 0.1s.
