TOGGLE MEMORY BURST

摘要

A controller (105) for a toggle memory that performs burst writes by reading a group of bits in the toggle memory (103) and comparing each received data word of the burst with a portion of the group to determine which cells to toggle to enter the data of the burst write in the toggle memory. In one example the toggle memory includes magnetoresistive random access memory (MRAM) with cells using multiple free magnetic layers that toggle between states when subjected to a sequence of magnetic pulses along two directions. Because one read is performed for a group of data of the burst, the time needed to perform the burst write is reduced.
