Memory address line and address digits, cable and word length, and addressing the problem

Time:10-02

A memory address line 6, data line 16 root,

1. Address line 6, whether to determine the memory of the memory unit is 2 ^ 6?

2. Cable 16 root, determine the word length is equal to 16?

3.
But if the byte (eight bits) addressing, memory unit has 2 ^ 7, that shall not be 7 address thread?
Such a word need two storage unit? So, CPU reads a data, it is a one time directly read a word, or memory access two consecutive times, read two memory unit combined into a word again?

1, 2, understand there should be no problem, 3 to see whether the memory is there pattern choice; If you have, in bytes read mode, there may be pin reuse, address will be extended to seven, refer to the data sheet of memory used,

is CPU access memory at a time, please read a word or a memory location?

Associated with the processor's data bus and its working mode; 32-bit processor is generally read a word,
