You can do simply like this:
var Memory = {
personAbove: "someone",
words: [] //Now you can add any value is array
}
You can parse this array value like this: Memory.words or Memory['words'] whichever you like.

You can make array inside an object
var Memory ={
personAbove: "someone",
words: {
wordsMem:["a","b","c"]
}
}
to access values inside array
Memory["words"]["wordsMem][0] //a
or
Memory.words.wordsMem[0] //a

Objects are constructed using key value pairs, so "personAbove" is a key for the value "someone". Similarly an array is a value, so all you need is a key.
let Memory = {
personAbove: "someone",
words: []
}
Sets the empty array as the value of Memory.wordsMem. Alternatively, you can define the wordsMem variable first, then reference it as the value of the words key.
let wordsMem = [];
let Memory = {
personAbove: "someone",
words: wordsMem
}
This sets wordsMem and Memory.words to point at the same array, so performing array operations on one will update the other.
