Study Notes
SRAM vs DRAM
- SRAM uses transistors, requiring constant power to maintain data. It's faster than DRAM.
- DRAM uses capacitors to store data, needs periodic refreshing, making it cheaper and larger than SRAM.
Integrated Circuit (IC) Types
- Digital ICs: Used in computer memories and microprocessors.
- Analog ICs: Handle continuous signals; examples include amplification.
- Mixed ICs: Combine both digital and analog functionalities.
Integrated Circuit Advantages
- Low power consumption
- High reliability
- Low cost
- High-speed operation
Cache Memory
- Small, fast memory in the CPU.
- Stores frequently accessed instructions and data.
- Reduces access time from slower main memory, improving CPU performance.
Registers
- Hold data memory addresses, next instructions, and intermediate results.
- Act as a transit between main memory and processor, enabling quick access to essential data.
Programmable ROM (EPROM)
- Read-only memory, erasable and reprogrammable using electrical signals.
- EEPROM: Easier erasure and reprogramming compared to UV-EPROM.
- UV-EPROM: Erasure uses ultraviolet rays.
Secondary Memory Characteristics
- Non-volatile; data persists even when the computer is off.
- Slower than primary memory.
- Used for long-term data storage.
- Can use magnetic and optical methods to store data.
Integrated Circuit Types Based on Technology
- Monolithic: Designed on a single piece of silicon or semiconductor.
- Bipolar: Uses bipolar transistors, operating in saturation/cutoff regions.
MOS Circuit Types
- NMOS: More n-type areas than p-type.
- PMOS: More p-type areas than n-type.
Integrated Circuit Disadvantages
- Lack of transformers and inductances.
- Replacement of entire circuit if one component fails.
- Less flexibility in design.
Cache Memory Function
- Stores frequently accessed instructions and data in a faster memory area within the CPU.
- Reduces retrieval time from slower main memory.
- Improves overall CPU efficiency and speed.
CMOS Circuit Types
- Static CMOS: Maintains its state without needing constant refreshing.
- Pseudo-nMOS: Uses a different method to achieve similar results as Static CMOS, generally with lower power consumption.
Integrated Circuits in Memory Devices
