I think it should be 23 cause it is 1 MB (Mega Bytes)= 1024 x 1024 x 8 bits are there so address lines = 10 + 10 + 3 = 23 . Had there been 1 Mb(Mega bits) of data then answer will be 20 .

20 address lines are needed for 1MByte of Data. Lets calculate other way aroundNo Of address lines 20 ..... so 2 power 20 = 1048576 (can address locations) So one location is 8 bit = 1048576 * 8 = 8388608 bits.And 1Mbyte of data = 1024 Kbyte = 1024 * 8 Kbits =1024 * 1024 *8 bits = 8388608 bitsHope this clears everything.

1MB = 2^20
Address Lines: log_2 (2^20) = 20
