Study Notes
SRAM vs DRAM
- SRAM (Static Random Access Memory) uses transistors, needs constant power, and is faster.
- DRAM (Dynamic Random Access Memory) uses capacitors, needs refreshing, is cheaper and larger than SRAM.
Integrated Circuit (IC) Types
- Digital ICs: used in computer memories and microprocessors.
- Analog ICs: handle continuous signals for functions like 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, faster memory located in the CPU.
- Stores frequently accessed instructions and data.
- Reduces time retrieving data from slower main memory, improving CPU performance.
Registers
- Hold memory addresses of data, next instructions, and intermediate results.
- Act as transit storage between main memory and processor, speeding up data access.
Programmable ROM (EPROM)
- Read-only memory that can be erased and reprogrammed using electrical signals.
EPROM vs EEPROM vs UV EPROM
- EPROM uses ultraviolet rays to erase.
- EEPROM allows for easier erasure and reprogramming.
Secondary Memory Characteristics
- Non-volatile; data persists even when the computer is turned off.
- Slower than primary memory but needed for extensive data storage.
- Consists of magnetic and optical memories
Integrated Circuit Technologies
- Monolithic: single piece of silicon.
- Bipolar: uses bipolar transistors operating at saturation or cutoff
MOS Circuits
- NMOS: more N-type areas than P-type.
- PMOS: more P-type areas than N-type.
Integrated Circuit Disadvantages
- Absence of transformers and inductance.
- Need for replacing entire circuit if one component fails.
- Limited flexibility in design.
Cache Memory Function
- Holds frequently accessed instructions and data in a faster memory within the CPU.
- Speeds up data retrieval from slower main memory, improving system efficiency.
CMOS Circuits
