The NS4165B is typically packaged in a compact, surface-mount type known as a QFN (Quad Flat No-lead) package. This design allows for efficient thermal management and space-saving on printed circuit boards (PCBs).

The NS4165B is a dynamic RAM (DRAM) memory chip that typically features a pin count of 28. Its primary function is to store data in a volatile memory format, meaning it requires constant power to maintain the stored information. The NS4165B is organized as 65,536 bits, or 8 kilobytes, and operates on a 16-bit data bus.
The key pins include:
- Address Pins (A0-A13): Used to select the specific memory location.
- Data Pins (D0-D7): Allow for data input and output.
- Control Pins: Such as Chip Select (CS), Write Enable (WE), and Output Enable (OE) for controlling read and write operations.
This chip is commonly used in various computing applications where temporary data storage and quick access speeds are required.
