Serial Memory Products

A broad portfolio of high performance, best-in-class Serial Memory Products

to meet all your design requirements.

Microchip offers the broadest range of Serial EEPROM devices (from 128 bits to 1 Mbit) over the widest operating

voltage (1.7 to 5.5V) and temperature ranges (up to 150ºC). Innovative low-power designs and extensive testing

have ensured industry leading endurance and best-in-class quality at low costs.

SPI-compatible Serial SRAM devices are available in 64 and 256 Kbit options and up to 20 MHz. These low power

devices provide additional external serial RAM with high-speed performance and are available in standard 8-pin

packages.

Serial SRAM

Do you need a simple, inexpensive way to add RAM to

your application? Microchip offers external RAM where

you need it.

Microchip’s new serial SRAM family provides a way to easily and

inexpensively add external RAM to almost any application. These serial

/

devices use less power and fewer I O connections than traditional parallel

SRAM. And, they allow designers to use a smaller microcontroller rather than

moving to a larger microcontroller just to get more on-board RAM.

Wafer-Level Burn-In

Microchip’s best-in-class field performance is the combined result of world class

manufacturing, wafer level burn-in and wafer probe quality screens.

Microchip’s Triple Test Flow is currently the most robust testing procedure for serial EEPROM devices in the

industry. It tests each cell of each die three times and also performs extensive endurance and data retention tests

to ensure quality and reliability.

Infant mortality of Microchip serial EEPROMs is among the lowest in the industry due to this extensive testing,

excellent fabrication and highly reliable memory cell design.

Microchip’s Triple Test and

Wafer-level Burn-in Procedure

Traditional Burn-in

(Old Technology)

Moving beyond traditional burn-in to wafer level burn-in with the Triple

Test Flow specifically targeted for memory cells has helped create the

industry’s most reliable memory products.

General purpose non-specific testing procedure

for random logic cells

■

Extensive Testing – Every cell in every die is tested three times,

including specific endurance and data retention tests to ensure

highest quality.

■

Non-specific and untargeted testing

mechanism – Increases failure rates.

■

Expensive, time consuming and inefficient.

Introduces defect modes like bent leads

and EOS that sometimes go undetected.

■

HVST, LVHF and TVPP tests target specific defects.

Maverick, SBY and GBN target overall failure patterns and trends.

Insight into failure modes along with flexible test flow ensures

continues improvement.

Microchip tests every cell in wafer form twice, then performs a final test after assembly.

Wafer Probe Quality Screens

Microchip performs additional in-house testing during wafer

probe to ensure quality and eliminate any devices that are

outside the normal distribution or might possibly fail in the

future.

High Voltage Stress Test (HVST)

HVST targets weak devices with oxide defects in RAM and logic

circuits by stressing the oxides at higher than normal voltages.

Time at Vpp (TVPP)

Rejected by

TVPP targets oxide defects in EEPROM cells, charge pumps

and other high-voltage circuits. Programming voltages (VPP) are

applied to the memory array for an extended period of time in

order to highlight any weak devices.

(Concept)

Low Voltage High Frequency (LVHF)

What Does All of This Mean?

LVHF targets signal paths that are partially blocked and therefore

more resistive than normal. LVHF eliminates these devices by

requiring them to operate faster than specified and at voltages

lower than specified.
