Latch Up immunity for 65mn
Cypress has completed Latch up testing for the current 72Mb QDR2+ product.
The 144M design will incorporate the same architecture and circuitry.
Results from 72M QDR2+ 62MN product:
-Voltage Stress up to 2.5: 0 FIT
-SEL (Neutron Testing) 2.5V up to 125C: 0 FIT
| 144MB QDRII+ SRAM | ||
|---|---|---|
| SER | Logical Single Bit Upset (LSBU) | 400 |
| (FIT/MB) | Logical Multi Bit Upset (LMBU) | 0 |
| (All Temp.) | Physical Single Bit Upset (SBU) | 280 |
| Physical Multi Bit Upset (MBU) | <20% of SBU | |
| SEL (FIT/MB) (All Temp.) | <0.1 | |
