The TMS4464-10NL is a dymanic Random Access Memory (RAM) DIP18 IC. 

TMS4464-10NL is a type of random access memory (RAM) chip that is used in electronic devices to store data temporarily while the device is in use. It is a dynamic RAM (DRAM) chip, which means it stores data using capacitors and requires periodic refreshing to maintain the stored data.

The TMS4464-10NL is a specific product that is manufactured by Texas Instruments and is available in a DIP-18 package, which is a type of integrated circuit package that has 18 pins and can be inserted into a DIP socket on a circuit board. The chip has a capacity of 10,048 bits of RAM, which allows it to store a small amount of data temporarily while the device is in use.

RAM chips like the TMS4464-10NL are commonly used in a variety of electronic devices, including computers, laptops, tablets, smartphones, and other devices that require temporary data storage. They are an essential component of these devices, as they allow the device to access and process data quickly and efficiently. It is important to note that RAM chips may be sensitive to static electricity and other forms of damage, and it is important to handle them with care.
