Only the various types of ROM: masked ROM, programmable ROM, UVPROM, EEPROM, NOVRAM (which is a SRAM and a EEPROM backup memory on one chip that automatically programs the contents of the entire SRAM in one programming cycle to the EEPROM when power is switching off and then automatically reloads the SRAM with the contents of the EEPROM the moment power is switched on and stable), Flash memory (which performs large "sector" programming cycles instead of individual byte programming cycles, allowing it to act as a solid state disk drive), etc. retain data without power.
There has been work on magnetic RAM chips (MRAM) that like the old magnetic core memory stacks will retain memory without power, but they have never been able to be produced at a cost comparable to modern DRAM.
What else can I help you with?
When you tune your car radio the stations clear when the engine is switched off?
it need a continuous 12volt power supply for the memory
Read only memory - keeps its memory even when the computer is turned off?
Yes, ROM (Read Only Memory) retains its contents even when the computer is turned off. RAM (Random Access Memory), on the other hand, loses its content the instant power is switched off.
What does SMPS stand for?
SMPS stands for switched mode power supply
What is the full form of SMPS?
Switched Mode Power Supply
What is a type of computer memory that retains content until loss of power?
RAM
Is EEPROM a volatile or nonvolatile memory?
Non-volatile. It retains its memory even if power is removed.
Will more memory need a bigger power supply?
To add more memory cards you do not need a larger power supply. To add more hard drives for more memory storage space you might need to increase power supply.
What is another name for memory when all data is lost if power is switched off?
RAM
Is RAM memory volatile?
Yes it is. Volatile memory is computer memory that requires power to maintain the stored information; it retains data while powered, but when power is lost data is immediately lost.
Is cache memory non volatile memory?
No, cache memory is a volatile type of memory, meaning the data stored in cache memory is lost when the power is turned off. Non-volatile memory, on the other hand, retains data even when the power is turned off.
Is a phone charger a switched mode power supply?
not all but there rare many of them in this usage
What is rectification and which power supply provides a smoother form of rectification with less fluctuation?
Rectification is the process of converting alternating current into direct current. The smoothest power supply is a 'switched mode' supply.
