Memory cycle time is the minimum time delay required between the initiation of two successive memory operations, for example, the time between two successive Read operations. So in this case it will take a time of 1 $\mu s$ to issue two successive operations.

64 bit word length means, CPU can access 64 bits in one go. So you can perform operations on one whole word, rather than bit by bit. That's why data bus size, instruction size, address size are usually multiples of the word size.
