A 1Mx64-bit memory chip contains , or 64-bit Lwords..
You could express this either in terms of MegaBits or MegaBytes..
In Megabits, 64Mbits because 1Mx64 = 64Mbits.
and …divide by 8 to get the answer in terms of bytes. You divide by 8 because there are 8 bits in 1 byte..
So a 1Mx64-bit memory contains 8 Mbytes, or 64 Mbits..
If the width had been 1Mx32-bit, you would have 32Mbits, and 4 Mbytes. (MORE)
