Layout of an SSD

Introduction

A Solid-state drive (SSD) is a nonvolatile electronic storage medium used in computers and laptops. An SSD is a secondary storage device that uses flash memory.

Types of ROM

Before discussing the layout of SSD, let's understand the different categories of ROM and where flash memory falls in the category.

Read-only memory (ROM) or firmware is a memory technology used when the data is written once and not changed. Computers use this storage technology when the information is stored permanently, even when the power is off. As a result, they are durable and less expensive than RAM technologies.

ROM is categorized based on the number of program/erase (P/E) cycles it can handle, which is the number of times the chip can be erased and programmed before it becomes unusable.

Types of ROM include:

• Masked Read-Only Memory (MROM): MROM is a read-only memory chip programmed during manufacturing. It cannot be erased or rewritten.

• Programmable Read-Only ...
