(3) Prior to burn-in, the devices shall be programmed (see 3.8.31 with the data pattern shown on figure 5. The pattern shall be read before and after burn-in. Devices ha
33、ving bits not in the proper state after burn-in shall constitute a device failure and shall be included in the PDA calculation (see 4.2). equivalent). b. Interim and final electrical test parameters shall be as specified fn table II. Interim electrical test parameters prior to burn-in shall be perfo
34、rmed by the manufacturer. The following data patterns shall be included in group A, subgroups 7 or 8 (high and low temperature): All Os, all lse checkerboard, and checkerboard complement. Each temperature shall include, at a minimum, the programming of one data pattern. Subgroups 9, 10, and 11 shall

Percent defective allowable (PDA): The PDA for class S and B devices shall be as specified in MIL-M-38510. The PDA is specified as 5 perce
36、nt for class 6 devices based on faflures from group A, subgroups 1 and 7 after cooldown, at final electrical test in accordance with method 5004 of MIL-STD-883, and with no intervening electrical measurements. All screening failures of group A, subgroups 1 and 7 after burn-in divided by the total nu
37、mber of devices submitted to burn-in in that lot shall be used to determine the percent defective for that lot, and the lot shall be accepted or rejected based on the PDA. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-M-38510/261 d. Those dev
38、ices whose measured characteristics, after burn-in, exceed the specified delta (A) limits or electrical parameter limits specified in table I, subgroup 1, are defective and shall be removed from the lot. The verified failures divided by the total number of devices in the lot initially submitted to b

40、tions: (1) Cycling may be block, byte, or page at equipment room ambient e. An endurance test including a data retention bake, in accordance with temperature and shall cycle all bytes for a minimum of 10,000 cycles for device types O1 through 05 and 07 through 11, and a minimum of 50,000 cycles for
41、device types 06 and 12. After cxcling, perform a high temperature unbiased bake for 48 hours at +150.C, minimum. The storage time may be accelerated by using higher temperature in accordance with the Arrhenius Relationship: (2) “1 -572 - 1 - AF = e AF = acceleration factor (unitless quantity) = tl/t

(3) Read the data retention pattern and test using subgroups 1, 7, and 9 (minimum, e.g., high temperature equivalent subgroups 2, 8A, and 10 may be used
44、) after cycling and bake, prior to burn-in. Devices having bits not in the proper state after storage shall constitute a device failure and shall be removed from the lot. using an apparent f. After the completion of all screening, the devices shall be erased and verified prior to delivery. 4.3 Quali
45、fication inspection. Qualification inspection shall be those in accordance with MIL-M-38 510. Inspections to be performed shall be those specified in method 5005 of MIL-STD-883 and herein for groups A, B, C, and D inspections (see 4.4.1 through 4.4.4). 4.3.1 Qualification extension. When authorized
46、by the qualifying activity, for qualification inspection, if a manufacturer qualifies to a faster device type which is manufactured identically to a slower device type on this specification, the slower device type may be part I qualified without further qualification testing. At the manufacturers re
47、quest, the slower device types will be added to the QPL. 4.4 Quality conformance inspections, Quality conformance inspection shall be in accordance with MIL - M 38 510.
