However, until now MRAM power consumption has exceeded that of SRAM, throwing up a major barrier to practical application.

It also makes cellular phones and the crucial SRAM (synchronous random access memory chips) that are used inside them.
Also, Microchip came up with four new devices for its serial SRAM portfolio.
It minimizes the active power of the SRAM in certain conditions by monitoring the current consumption of the SRAM rest circuits.

It also has 2.5 KB of SRAM and 1 KB of EEPROM (which can be read and written with the EEPROM library).

As low performance applications require only tens of MHz operation, SRAM temperature remains around RT, where active and leakage power consumptions are comparable.

MRAM, a next-generation memory based on magnetic materials, has emerged as an alternative to SRAM because it is non-volatile, cutting leak current during standby status.

However, improving the performance of SRAM to match advances in mobile products results in increasing current leakage, both during operation and in standby mode, degrading power performance.

But Day believes millions of desperately poor people, trapped by lousy infrastructure, can achieve a better life through bicycles--albeit not the kind of bicycles that Sram and its customers make.
And while DRAM is strong enough to handle complex software, it's slow: When the PC needs to crunch numbers, it must resort to far faster memory cache, also called SRAM (static random access memory).
Until now SRAM has provided the cache-memory solution.

Under the hood there's a 240Mhz ARM processor, which has DSP and Java acceleration built in, and 16MB of SRAM, expandable to 128MB, giving the player enough juice to run Adobe Flash and Java apps with future firmware upgrades.
By putting it into volume production in NAND flash, the company will have gained a deep understanding and will have a very mature process by the time it decides to use double patterning to make the SRAM caches on its processor chips.
TOKYO-Toshiba Corporation (TOKYO: 6502) today announced that the company has developed a prototype memory element for a spin transfer torque magnetoresistive random access memory (STT-MRAM) that achieves the world's lowest1 power consumption yet reported, indicating that it has the potential to surpass the power consumption efficiency of SRAM as cache memory.
