一、概述公司
备忘录是一种录以备忘的公文。在公文函件中，它的等级是比较低的，主要用来提醒、督促对方，或就某个问题提出自己的意见或看法。在业务上，它一般用来补充正式文件的不足。它的内容可以分为以下几项：
书端(Heading);
收文人的姓名、头衔、地址(Addressee’s Name, Title, Address)；
称呼(Salutation)；
事因(Subject)；
正文(Body) ；
结束语(Complimentary Close)；
署名(Signature)。
二、注意事项
书端部分包括发文机关的名称、地址、发文日期，有的还包括电报挂号、电传号、电话号码等。许多机关有自己特制的信笺，在写书端时，其格式和标点符号的使用与一般信件的相同。收文人(或收文单位)的姓名、头衔、地址一项写在左上角编号处的下面，其格式与书信的写法相同。
称呼从左边顶格写起，对一般机关、团体的负责人一般用 Dear Sir， 对政府官员可用 Sir。
“事因”一项目前采用得较少。它可放在称呼语之前，也可放在其后，前面可加 Re或Docket, Subject。如果此项写在称呼语之前，多从左边的顶格写起；若放在称呼语之后，一般写在信笺正中。它多采用不完整的句子，只需很少几个词，甚至一个词，目的在于使收文人对文中的主要内容一目了然，便于及时处理。
正文、结束语和署名等项与一般信件的格式相同。
例子一：
The heading segment follows this general format:
TO: (readers' names and job titles)
FROM: (your name and job title)
Date: (complete and current date)
SUBJECT: (what the memo is about, highlighted in some way)
Make sure you address the reader by his or her correct name and job title. You might call the company president "Maxi" on the golf course or in an informal note, but "Rita Maxwell, President" would be more appropriate for a formal memo. Be specific and concise in your subject line. For example, "Clothes" as a subject line could mean anything from a dress code update to a production issue. Instead use something like, "Fall Clothes Line Promotion."
