AEHR TEST SYSTEMS REPORTS FINANCIAL RESULTS
FOR FOURTH QUARTER FISCAL 2011

Fremont, CA (July 19, 2011) - Aehr Test Systems (Nasdaq: AEHR), a worldwide
supplier of semiconductor test and burn-in equipment, today announced
financial results for the fourth quarter and full-year ended May 31, 2011.

Net sales were $3.7 million in the fourth quarter of fiscal 2011, compared
with $3.6 million in the fourth quarter of fiscal 2010.  Fiscal 2011 full-year
product sales were $13.7 million, compared to fiscal 2010 product sales
of $8.9 million.  Fiscal 2011 full-year net sales were $13.7 million, compared
to net sales of $11.7 million in fiscal 2010 which included the positive
impact of $2.7 million resulting from cancellation charges related to the
Spansion bankruptcy claims.

Commenting on the fourth quarter and full-year results, Rhea Posedel,
chairman and chief executive officer of Aehr Test Systems, said, "We took
steps in the right direction during fiscal 2011 and demand for our products
continues to improve.  On a year-over-year basis, fourth quarter product
sales increased slightly, while full-year product sales were 54% higher
than the previous year.  During the fourth quarter, we benefitted from over
$2 million in follow-on orders for FOXTM-1 WaferPak contactors for wafer
sort testing.  We believe that these orders are an indication of the cost
and through-put benefits that can be achieved utilizing our FOX-1 full-wafer
test products."

Aehr Test reported a net loss of $144,000, or $0.02 per diluted share, in
the fourth quarter of fiscal 2011.  This compares to a net loss of $819,000,
or $0.09 per diluted share, in the fourth quarter of fiscal 2010.  Net loss
in the fourth quarters of fiscal 2011 and fiscal 2010 included proceeds
related to the Spansion bankruptcy claims of approximately $677,000 and
$120,000, respectively. Net loss for the year ended May 31, 2011 was $3.4
million, or $0.38 per diluted share, compared with a net loss of $481,000,
or $0.06 per diluted share, in fiscal 2010. Net loss in fiscal 2011 and
fiscal 2010 included aggregate proceeds related to the Spansion bankruptcy
claims of approximately $832,000 and $6.7 million, respectively.  As of
May 31, 2011, the company's backlog was $5.8 million, compared with $2.5
million at May 31, 2010.

Posedel concluded, "Looking ahead, we remain confident that our operating
momentum will continue into fiscal 2012.  The potential sales opportunities
we see for ABTSTM systems and FOX products in fiscal 2012 are very
encouraging."

1 The Company filed claims in the Spansion U.S. and Spansion Japan bankruptcy
actions.  In the first quarter of fiscal 2010, the Company sold a portion
of its Spansion U.S. bankruptcy claim to a third party for net proceeds
of approximately $3.3 million and recorded the amount as a reduction of
operating expenses.  In the third quarter of fiscal 2010, the Company sold
the remaining balance of its Spansion U.S. bankruptcy claim for net proceeds
of approximately $4.6 million and recorded $2.7 million as revenue related
to cancellation charges, $1.3 million as deferred revenue, and $0.6 million
as a reduction of operating expenses.  In the fourth quarter of fiscal 2010,
the Company received the remaining payment of $0.1 million due from its
Q1 bankruptcy claim and recognized the amount as a reduction of operating
expenses.  In the first quarter of fiscal 2011, the Company's Japanese
subsidiary received approximately $155,000 in proceeds from the Spansion
Japan bankruptcy claim and recorded the amount as a reduction of operating
expenses.  In the fourth quarter of fiscal 2011, the Company's Japanese
subsidiary received approximately $677,000 in proceeds from the Spansion
Japan bankruptcy claim and recorded the amount as a reduction of operating
expenses.

Non-GAAP net income is a non-GAAP measure and should not be considered a
replacement for GAAP results.  Non-GAAP net income is a financial measure
the Company uses to evaluate the underlying results and operating performance
of the business.  The limitation of this measure is that it excludes items
that impact the Company's current period net income.  This limitation is
best addressed by using this measure in combination with net income (the
most comparable GAAP measure).
