Always there are few set of items needs to be memorized in short span of time. Here are my following cases.

1) My Job requires some set of items needs to be memorized.
2) I am a developer who has to learn 150+ tags within next 3 days.
3) Fix developer/support has to remember minimum of 125+ tags (set of possible values).
4) It is better if team's SQL developer knows all the table and columns in my database.
5) When guys join new department or job. Memorizing few related items will definitely gives some benefit.

Most of the cases, I suggest people to understand the domain better and nothing wrong in using google (but remember correct search-word). But recently I came across a junior developer who took lot of effort in memorizing set of things (150+ table structures, fix protocol tags, almost 300+ configuration items from property file) and was very very successful in his job and was swift in responding for support queries. Needless to say he is smart worker too (not a dumb guy).

When I try to recollect some of the successful employees I met, they were so good in remembering entire schema and they did in short span of time. But I don't argue that memorizing alone gives success, but it greatly helps when situation demands.

Here my question is, I am not good at remembering things, but it shouldn't be lame excuse. Hence I am evaluating using technolgies better to memorize set of items. Not very much interested in memory techniques (mnemoninc, photography memory, etc..). Even I have recorded 100+ items and listen to that whenever I found free time, defintely there were some fruitful result. Now I need your suggestion about what are all the ways to exploit technology to memorize.

There could be so many reason why guys remember a subject (passionate, essential, author, creator, responsbile). Not interested in dissecting why guys remeber. Rather much interested in using ways, and techniques (cheat sheet...) to remember a set of itmes.

Note : I appreciate, encourage people who could rephrase my question better.
Note : I have kept couple of cheat-sheet close to my monitor, honestly it did not help me :).
