MB85RS512TPNF-G-JNERE1 Overview

Memory FeRAM 512K (64 K x 8) Bit SPI MB85RS512TPNF-G-JNERE1


MB85RS512TPNF-G-JNERE1 is a specific model of Ferroelectric Random Access Memory (FeRAM) chip that has a capacity of 65,536 words, with each word consisting of 8 bits. The chip uses both ferroelectric and silicon gate CMOS process technologies to form non-volatile memory cells.

FeRAM is a type of memory that uses a ferroelectric material to store data. Ferroelectric materials have the unique property of being able to keep their polarization state even after the electric field is removed. This property makes FeRAM a type of non-volatile memory, meaning that the data stored in it is retained even when the power is turned off.

The use of silicon gate CMOS process technologies in the formation of non-volatile memory cells helps to make the chip more reliable and durable. FeRAM chips are known for their high read and write speeds, low power consumption, and long data retention times, which make them useful in a wide range of applications such as automotive, industrial, and medical devices, as well as in consumer electronics.
