Smart Card IC
typically utilizes one or more of the following types of memory: RAM, ROM, PROM,
and EEPROM, embedded on a die that contains the CPU
and Control Logic.
Significant system overhead is required to manage these different types of
memory.

EMRAM as Embedded Memory on Smart Card IC
As embedded memory on Smart Card IC, EMRAM is a high
performance yet low cost alternative:
-
Improves IC
performance by utilizing a single fast non-volatile memory architecture. -
Lowers IC cost
by enabling a significantly smaller die. -
Lowers
operating and set up cost by enabling application coding flexibility and
easy version upgrades. -
Lowers
inventory and design cost by enabling the consolidation of IC designs.

Key Features
|
-
Very Fast Read & Write
- Read and write
times are typically less than 50ns.-
Data Storage
Endurance
-
EMRAM is non-volatile,
and retains data ad infinitum.
-
Read/Write
Endurance
-
With an infinite
endurance theoretically, EMRAM has been tested to endure > 1015
Read / Write
cycles.
Simple Memory Management
-
EMRAM
uses a single Voltage for Read / Write.
-
It has a random
addressable data structure.
Enables Coding Flexibility
-
Read-Only sectors are
created post IC fabrication during programming. Application codes
need not be designed into the machine code of the IC.
|
-
Smallest
Silicon Footprint
-
When embedded, EMRAM layers sit
on top
of the
Logic IC. This could reduce chip surface area by up to 50%,
significantly increasing the number of chips per wafer, and
lowering unit cost as a result.
-
With an
1T-16bit architecture, EMRAM takes up significantly less space than
SRAM and EEPROM.
-
Low Power
-
Radiation Hardened
Elevated Temperature Endurance
-
EMRAM storage layers
are stable beyond 200˚C
with
compatible silicon substrates.
