How about the Microchip 256Kbit serial SPI SRAM chip 23K256? Today I will give you a detailed introduction.

Serial SRAM is a self-contained volatile memory that provides an easy and inexpensive way to add more RAM to your application. These 8-pin low-power, high-performance SRAM devices have unlimited endurance and zero write time, making them ideal for applications involving continuous data transfer, buffering, data logging, audio, video, Internet, graphics, and other math and data-intensive Ideal for applications. And supports SPI, SDI and SQI bus mode.

The Microchip Model 23K25 is a 32,768-byte serial SPI SRAM that interfaces with the Serial Peripheral Interface (SPI) ports of many popular microcontroller families by using discrete I//I that are properly programmed in firmware to match the SPI protocol. The O line is connected to microcontrollers that do not have a built-in SPI port.

The 23K256 capacity is a serial SPI SRAM device with a capacity of 256Kbit. The memory is accessed through a simple serial peripheral interface (SPI) compatible serial bus. The required bus signals are the clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through the Chip Select (CS) input. Communication with the device can be suspended via the hold pin (HOLD). When the device is suspended, transitions on its inputs are ignored, except for chip selects, allowing the host to handle higher priority interrupts. The 23K256 is available in standard packages, including 8-pin PDIP and SOIC, and advanced packages, including 8-pin TSSOP.
