NETSOL MRAM replaces traditional low-power ISSI SRAM battery backup

Many stock embedded project boms use ISSI SRAM as the external cache.In order to realize power-off storage,SRAM with backup battery is generally adopted.But now the supply of some models of ISSI is unstable,and the shortcomings of battery backup scheme are becoming more and more obvious.Many people begin to seek the replacement of ISSI SRAM,and the NETSOL STT‑MRAM represented by RAMSUN is a good alternative direction.
 

The traditional ISSI low-power SRAM relies on six transistors to latch data,which has excellent read-write delay,but it does not have the ability to save when power is off.The whole backup system involves battery,power supply monitoring and switching circuit.If any device is abnormal,all parameters and logs will be lost.For unattended industrial equipment,the later maintenance cost is not low.
 

NETSOL MRAM uses 1 TMTJ memory cell,which records information by magnetic moment state without charge to maintain data.The parallel version package includes 44TSOP2 and 48FBGA,which are matched with many ISSI low-power SRAM package pads,and support pin‑to‑pin for compatibility evaluation.NETSOL MRAM chip has micro-ampere-level sleep power consumption,ultra-high erasure durability,eliminating the whole set of battery peripheral circuits and simplifying the hardware design of the whole machine.
 

If you are carrying out alternative evaluation of MRAM storage,you can submit the original ISSI device model,voltage,temperature,service reading and writing conditions,and apply for scheme evaluation and sample testing.
