The world’s only logical / application hybrid DRAM tester, now added Physical Memory Repair function. It not only performs testing on DDR4 Memory Module but also repairs failure memory portion based on application test result. The tester makes production higher in yield, and lower in cost.
KT-4MG+ is the world’s first DIMM tester that supports Physical Memory Repair*, based on application test result memory can be repaired to increase product yield. This technology is based on Post Package Repair standard which is defined by JEDEC.
KT-4MG+ has two modes of PPR Memory Repair:
- Soft Post Package Repair (sPPR): sPPR is non-persistent, so the repair row maybe altered; that is, sPPR is NOT a permanent repair, so the repair is cleared after the device is power reset
- Hard Post Package Repair (hPPR): Hard Post Package Repair is persistent so once the repair row is assigned, the device stays as permanent repaired good. hPPR is limited by on-die repair resources. KT-4MG+ can allow the user to maximize repair resource usages by analyzing the device error log obtained from priori tests.
*Note: Please refer the JEDEC standard, and the specification of your selected memory.
