SRAM is “static” in the sense that if the power is turned off, SRAM will continue to store data (e.g. as in flash memory in MP3 players or USB thumb drives). In the two’s complement number representation, a negative number with more leading ones is larger (i.e. less negative) than a negative number with fewer leading ones. For numbers represented in two's complement form, the negative of a number can be found by adding one and then inverting the bits.

You can't arbitrarily perform sign extension if you have a fixed format, which is the case here. 1 votes 1 votes Please log in or register to add a comment.
1 votes 1 votes hey bikram In the two’s complement number representation, a negative number with more leading ones is larger (i.e. less negative) than a negative number with fewer leading ones. It is like ambigous statmnt make it more clear.

For example, 1110 is same as 110 in 2's complement repreentation, isn't it? 0 votes 0 votes Arjun commented Apr 23, 2017 reply Follow Share @Shraddha No. For a given representation we have to assume a "fixed" no. of bits. Also, 2's complement and 2's complement representation are not the same. 3 votes 3 votes shraddha priya commented Apr 23, 2017 reply Follow Share ok.
