This article mainly introduces "what are the similarities between serial SRAM and FRAM". In daily operation, I believe many people have doubts about the similarities between serial SRAM and FRAM. Xiaobian consulted all kinds of data and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "what are the similarities between serial SRAM and FRAM?" Next, please follow the editor to study!

Although static RAM and ferroelectric RAM can have completely different uses, with the emergence of standard interfaces such as SPI, these technologies have a great overlap in functions. In this article, Yuxin Electronics introduces in detail the common properties of SRAM and FRAM, which provides the main driving force for replacing serial SRAM in the design.

Similarities between SRAM and FRAM

SRAM and FRAM exhibit many similar features in many designs. Serial SRAM and FRAM have similar storage densities, can support completely random read and write access, and can get all the results without additional latency. Given that both parts have implementations that use the SPI interface, it is clear that these parts can be used interchangeably in most designs. The common attributes of these technologies are described in the following sections.

Memory capacity

The serial SRAM available on the market today supports capacities ranging from 64 Kbit to 1 Mbit. Today, FRAM devices range in capacity from 4 Kbit to 4 Mbit. In addition, the new version of FRAM that supports ultra-low power consumption will support higher capacity in the future, up to 16 Mbit.

Immediate read / write random access

Both SRAM and FRAM support immediate read or write operations. Other technologies may experience long delays in reading and / or writing. In addition, completely random addresses can be accessed using SRAM and FRAM without block size restrictions.

There is no SPI address that implements a specific boundary

Both SRAM and F-RAM support immediate read or write operations. Other technologies may experience long read and / or write delays. You can use SRAM and F-RAM to access completely random addresses without block size restrictions.

SPI standard implementation

Both SRAM and FRAM support the SPI interface. Serial SRAM products support SPI at lower density and support multi-bit dual SPI (DSPI) and quad SPI (QSPI) at 512 Kbit or higher density. Currently, current FRAM components only support SPI, while ULE FRAM devices support all SRAM interfaces. All of these implementations are provided in some form of 8-pin package.

Common functions of SRAM and FRAM technology

At the highest level, the basic functions of SRAM and FRAM are the same-from Kilobits to the capacity of a small number of megabytes of random access memory stored instantly in memory. The memory has no special configuration or page boundaries and supports standard SPI physical pin arrangement.

At this point, the study of "what are the similarities between serial SRAM and FRAM" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
