U61000

U61000 is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand U61000 rather than just read about it. In short: U61000 was the first 1-Mbit DRAM microchip produced in the German Democratic Republic by Zentrum Mikroelektronik Dresden in September 1988 based on CMOS technology. size: 12.60 mm x 4.53 mm DRAM organisation: 1024k x 1 Bit access time: 100 ns - 120 ns The first step in the project was to develop the chip, this was called U61000-1. After the design and technology were optimized, the U61000-2.1 was created.

Key takeaways

U61000 belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect U61000 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of U61000 from memory before moving on to harder problems.

Reference excerpt

U61000 was the first 1-Mbit DRAM microchip produced in the German Democratic Republic by Zentrum Mikroelektronik Dresden in September 1988 based on CMOS technology.

size: 12.60 mm x 4.53 mm DRAM organisation: 1024k x 1 Bit access time: 100 ns - 120 ns The first step in the project was to develop the chip, this was called U61000-1. After the design and technology were optimized, the U61000-2.1 was created. The final version for production was called U61000-2.2.

Worked examples

Example 1 — a first encounter with U61000

Start with the simplest possible case. Write down what U61000 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to U61000 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about U61000 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of U61000

In research: U61000 appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses U61000 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: U61000 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer hardware stubs, Computer memory, Goods manufactured in East Germany, so understanding it makes those chapters shorter.
In everyday life: Look for U61000 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
