Memory interleaving:

Basically you start access on the first word, then while you read the first word, the memory controller starts access on the second word, and while you read the second word, the memory controller starts access on the third word,

Now, depending on burst length, like 8 words, you can restart access on the first word again, while you are reading the fourth word, and start the cycle over again, until you reach the length of the burst length.

The iPX 420 did bit interleaving. the 8088 did byte interleaving, ( 8bit processor 1 word interleaving. ) the 8086 also did byte interleaving, the 286 did word interleaving, two bytes at a time, the 386 did word interleaving, 4 bytes at a time, but it had to start on a 4 word boundry for the first read.
