Memory Map & Addresses in 8085 Microprocessor - Tri State Logic Devices and Memory - Microprocessor

TL;DR

This video explains the concept of memory mapping and addresses in a microprocessor, including how to calculate address range and select memory chips.

Transcript

hello friends in this video we will study about the memory map and the addresses in the microprocessor so let's start with our topic in 8085 microprocessor we have 16 address lines so how many registers it can address we can have this by the calculation so 16 address lines are there we were having 2 raised to the power n equals to number of registe...

Key Insights

• 🫥 The number of address lines in a microprocessor determines its addressing capacity.
• 🫥 Memory chips require a specific number of address lines to address their registers.
• 🫥 Address lines are used to select memory chips and identify memory registers.
• 🐿️ The address range of a memory chip can be adjusted by modifying the chip select line.
• ❓ Binary and hexadecimal notations can be used to represent addresses.
• 👻 Memory mapping allows for the organization and identification of memory registers.
• 🐿️ The chip select line in memory chips is an active low signal.

Summary & Key Takeaways

• The number of address lines in a microprocessor determines the maximum number of memory registers it can address.

• Memory chips require a specific number of address lines to identify each register, with the remaining lines used for chip selection.

• The address range of a memory chip can be changed by altering the hardware of the chip select line.
