8bit Data Resistor With Logic Gates

when was a child I was just curies about how do computers store the memory and now i am a 14year boy from India and i found that the memory is stored in these resistors and i start developing my own resistor by making many connection of the different logic gates this project tells us that anyone can create a computer at home there is need to a lab to make functional computer my resistor can contain maximum 8bit of data and after the 6 trials i made my own 8bit Resistor which can store the 8bit of data the data is store in this resistor is in form of 0 and 1 which is equal to 1 bit of memory the 1 of memory the 1 means the voltage is on and 0 means voltage is off the resistor contain the 8 Individual D-latch which contain 1bit of memory which is equal to 0 or 1 this resistor store this data in loop system of logic gates which store the data until the clock signal is not high when the clock signal is high the input data is goes directly to the main place where is will store these resistor are found in RAMs which is a short time store memory and that's which the D-latch in the resistors are have the clock signal to erase the previous data stored in the RAM and store more new data the RAMs are use while a computer doing any calculation or performing any logical process in this memories the computer contain the side numbers calculation same as carry, borrow etc this memory can also work when i will develop my own calculator that can actually calculate the numbers by performing the logical process with the 0 and 1 data

this 8bit resistor just need some logic gates

1 two AND logic gates

2 two NOR logic gates

3 one NOT gate

this list it for only making a single bit data storage device which is called D-latch and we need 8 D-latch to make a 8bit resistor

the circuit diagram shown above is the circuit diagram of a 8bit resistor with 8 D-latch connection together so it can store 8bit of memory with the in RAM in this circuit diagram the words A,B,C,D,E,FG and H denote the stored data in the RAM and also the D-latch which store the data these words is only for my help in this circuit because to maintain the input data and stored data is not easy with tangle of wires these words help me to check weather all of D-latch are working correctly and storing the correct data in the memory and the bigger E on the side is the denote the enable\clock signal which controls the input data weather it will store or it will pass away from the resistor for a another resistor the other same words at the top is the stored data this the this resistor can be stored 8bit or 1byte because 8bit=1byte it means we need millions of resistors to store a bigger data for a complex or hard work for computer of devices which uses memory it means the 8bit resistor can be called as a 1byte storage device i choose this 8bit data because i don't have many logic gates ICs in this circuit i use four 7408 and 7411 ic for these all logic gates if i make it with transistors it will be very big in real life and even i made it in a virtual simulation and it was tough to remind the wires to connect to one D -latch to another one

the process of storing the data is very simple just give the data in the form of 0 and 1 and then set the enable signal high or turn on it the data will go through the D-latch and stored at their output after the turn off of the enable signal until the enable signa will high the previous data will stay stored it the output and the when the enable signal is off the data will pass away to another resistor and then this data will act as the input for another resistor i didn't make any wires so they can connect with other resistors if you want to do this so you can take s wire out of the circuit to do this these wire will come from the another output from the D-latch a simple D-latch contain two inputs and two outputs outputs the Q1 is the stored data wire and Q2 is the current data which will act as the inputs for a another resistor

the data resistor works in same way s a D-latch works a D-latch take data and then store it until the enable signal is high for example i want to store 1 in a D-latch as data the input signal is 1 and enable is high tis data will goes to the output Q1 and because the enable is high both AND gates take signal 1 at input and then one AND gate will take signal 1 and another will take inverse of this data due to NOT gate so the NOR gates after the AND gates will take signal 1 and 0 at one leg and another leg is goes to a different NOR gates it means the one NOR gate output is one input the another NOR gate like a feedback loop this so at the input of one NOR gate is 1and0 and it will give 0 to another NOR gate and this NOR have input 0 and 0 so output is 1 and this the data which we want to store when we turn off the enable the signal will inverse and only u output will change as the current data which will goes to the another resistor as input i know that this all inputs and outputs is so hard to remind or learn but believe on yourself if you love electronic you can definitely learn this hard input sand output system

1 History of the Data Latch

1. The Early "Trigger" (1918): The first electronic flip-flop (latch) was invented in 1918 by British physicists William Eccles and F.W. Jordan. It was initially called the "Eccles-Jordan trigger circuit," designed using two vacuum tubes to act as a memory element that could flip between two states.
2. Wartime Computing (1940s): These circuits were heavily used in the 1943 British Colossus codebreaking computer to store binary information.
3. Transistorization (1950s): With the invention of transistors, the vacuum tube-based trigger was replaced by transistors, significantly decreasing the size and power consumption of the latch.
4. Formal Classification (1954): The different types of latches and flip-flops (SR, D, T, JK) were formally organized and explained in Montgomery Phister’s 1954 course and subsequent book, Logical Design of Digital Computers.
5. Integrated Circuit Era (1960s-1970s): Latches became foundational in digital systems, often integrated into ICs to handle data storage, control circuits, and buffers. The 74LS373 Octal D-type transparent latch, for example, became a standard component for holding a byte of data.
6. Modern VLSI and Time Borrowing (1980s-Present): In Very-Large-Scale Integration (VLSI) design, latches are used for their "transparent" nature (allowing output to change as input changes) and "time borrowing" capability, which helps improve performance by distributing timing delay
