这是一个结合了您想要的大部分功能的示例:
\documentclass{article}
%% Packages and libraries needed for this MWE
\usepackage{tikz}
\usetikzlibrary{calc}
\usetikzlibrary{arrows.meta}
%% Two commands for representing content.
\newcommand\aeDiagonalNumber{100}
\newcommand\memorySixtyFive{%%'
\begin{minipage}{2.75cm}
\centering
char `a' in memory\par
(65 = ascii code)
\end{minipage}}
\begin{document}
\begin{tikzpicture}[x=1.25in,y=0.65cm]
%% Building the boxes representing memory locations
\foreach \x in {0,1,...,20}
{
\node[inner sep=1pt] (BL\x) at (0,-\x) {};
\node[inner sep=1pt] (UR\x) at (1,-\x+1) {};
\node (MM\x) at ($(BL\x)!0.5!(UR\x)$) {};
\draw (BL\x) rectangle (UR\x);
\edef\memoryNumber{\number\numexpr276314+\x\relax}
\node[anchor=south east] at (BL\x.north west) {\memoryNumber};
}
%% Label columns:
\node (MEMLOC) at ($(MM0)+(0,2cm)$) { \parbox{2cm}{\centering Memory Location} };
\node (ADDRESS) at ($(MEMLOC)-(0.75,0)$) {\parbox{2cm}{\centering Address} };
\draw [-{Stealth[scale=1.5]}] (MEMLOC) -- (MM0|-UR0);
\draw [-{Stealth[scale=1.5]}] (ADDRESS) -- ($(MM0|-UR0)-(0.75,0)$);
%% Drawing arrows spanning memory locations
\foreach \x/\y in {3/0,
7/4,
11/8}
{
\node (M\x-\y) at ($(BL\x)!0.5!(UR\y)$) {\aeDiagonalNumber};
\xdef\aeDiagonalNumber{\number\numexpr\aeDiagonalNumber+100\relax}
\draw[-{Stealth[scale=1.5]}] (M\x-\y) -- (BL\x) ;
\draw[-{Stealth[scale=1.5]}] (M\x-\y) -- (UR\y) ;
}
%% Adding content to memory location "18"
\node at (MM18) {65};
\node (RHS18) at (MM18-|UR18) {};
%% Adding a side note to memory location "18"
\node[draw,anchor=west] (BOX18) at ($(RHS18)+(1cm,0)$) {\memorySixtyFive};
\draw [-{Stealth[scale=1.5]}] (RHS18.center) -- (BOX18);
%%
\node (1byte) at ($(UR10)+(0.5,0)$) { \parbox{1.5cm}{\centering One location = 1 byte}};
\draw [-{Stealth[scale=1.5]}] (1byte) -- ($(1byte|-UR5)-(0,0.5)$) -- ($(UR5)-(0,0.5)$);
\end{tikzpicture}
\end{document}
