Dynamic random access memory (DRAM) chips: Also known as volatile memory chips because they lose memory once the power supply is removed. DRAM can only transmit a single line of memory and needs to be constantly refreshed to prevent the loss of memory bits.
Static random access memory (SRAM) chips: Non-volatile chips that are commonly used in portable battery-powered devices. Unlike DRAM, they do not need to be refreshed and do not immediately lose memory when the power source is disconnected.
First in, first out (FIFO) memory chips: Mainly used when memory is being transferred between different types of devices.
Erasable programmable read only memory (EPROM): The memory in these chips can be erased when exposed to ultraviolet rays. These chips can then be reprogrammed for a new set of data values.
Programmable read only memory (PROM) memory: Differs from other programmable memory chips as they can only be programmed once.The contents cannot be erased electronically or though ultraviolet rays.
