ABSTRACT:
A memory device can include a group of memory cells, which can be arranged in a column (100) that receives power by way of a first cell supply nodes (106-0to106-m). A current limiter (110) can be situated between first cell supply nodes (106-0to106-m) and a power supply (VH), and limit a current (llimit) to less than a latch-up holding current (lhold_lu) for the group of memory cells (100). In a particle event, such as an α-particle strike, a current limiter (110) can prevent a latch-up holding current (lhold_lu) from developing, thus preventing latch-up from occurring. Current limiter (110) can include p-channel transistors and/or resistors, and thus consume a relatively small area of the memory device.
