Differences between 记得 and 记住
The biggest help to clarify the difference is that 记住 has the result complement 住, which is used to express halt (e.g. 站住 stand still), and, by extension, firmness of the action (e.g. 忍住 withstand).
So 记住 literally means &quot;remember firmly&quot;, therefore &quot;bear in mind&quot;, with also the additional nuance of making an active attempt to remember.
Examples:

他刚说的话很重要，你一定要记住 = What he just said is very important, you must remember it.
中文语法例外太多，我记不住 = Chinese grammar has too many exceptions, I can't remember them.

记得 instead means simply &quot;to remember&quot;, &quot;to recall&quot;, without an active effort to remember firmly.
Examples:

我昨天晚饭吃了什么，我已经不记得了 = I already don't remember what I had for dinner yesterday
明天记得把垃圾扔掉吧 = remember to take out the trash tomorrow
你去超市记得给我买一些水果 = remember to buy me some fruit when you go to the market
