One-transistor one-capacitor cell boosts
FRAMs
A new 256Kbit two-wire serial FRAM product uses a newly developed one-transistor, one-capacitor (1T/1C) memory cell that significantly improves the cost-per-bit ratio of resulting FRAM products.
The latest 256Kbit two-wire serial FRAM product from Solid State Supplies uses a newly developed one-transistor, one-capacitor (1T/1C) memory cell that significantly improves the cost-per-bit ratio of resulting FRAM products "The introduction of the FM24C256-SE is a significant milestone for the ferroelectric RAM market", said Solid State Supplies Product Manager Matthew Cook

Ferroelectric RAM handles repeated rewrites
The FM24C04 4Kbit FRAM serial memory from Solid State Supplies is ideal for nonvolatile memory applications which require frequent or rapid writing.
"1T/1C FRAM technology lays the groundwork for memories that can combine the density of DRAM and the low power, equal read/write speed of SRAM with the nonvolatile storage capability of Flash or EEPROM".
Recent advances in ferroelectric materials and processing have eliminated the need for an internal reference capacitor within every cell in the ferroelectric memory array.
Instead, the new 1T/1C cell architecture uses a single capacitor as a common reference for each column in the memory array, effectively cutting the required cell area in half compared with Ramtron's existing 2T/2C architecture.
The new architecture significantly improves die leverage, which results in lower overall manufacturing costs.
The FM24C256-SE FRAM provides superior performance to industry standard EEPROM and nonvolatile RAM products in metering (solid-state utility metering, printers and copiers), telematics (automotive electronic systems) and communications (telephones, caller ID and short messaging services) applications.
The product is ideal for any application that requires fast write speed, high write endurance, and low write power.
Reading and writing continuously at bus speeds of up to 1MHz with virtually unlimited endurance, the new FM24C256 features low standby and operating currents and operates from a 5V power supply drawing 75uA for reads and writes at 100kHz.
The FM24C256 offers 10 years of data retention and is rated over the industrial temperature range of -40 to +85C.
