Detailed Description

A single memory cell in the simulated architecture.

Blocks serve dual purpose:

In the code segment: they represent instructions (opcode + operands)
In the data segment: the operand field stores data values

This is a lightweight value type (Flyweight pattern) — designed to be stored in large arrays efficiently.
