                  AEHR TEST SYSTEMS REPORTS FINANCIAL RESULTS
                        FOR FIRST QUARTER FISCAL 2010

Fremont, CA (September 30, 2009) - Aehr Test Systems (Nasdaq: AEHR), a
technology leader in the semiconductor test and burn-in equipment industry,
today announced financial results for the first quarter of fiscal 2010 ended
August 31, 2009.

Net sales were $1.3 million in the first quarter of fiscal 2010, compared
with $9.7 million in the first quarter of fiscal 2009.  Aehr Test reported
net income of $1.0 million, or $0.11 per diluted share, in the first quarter
of fiscal 2010, compared with net income of $0.9 million, or $0.10 per diluted
share, in the first quarter of fiscal 2009.  Net income in the first quarter
of fiscal 2010 included a pre-tax gain of approximately $3.3 million from the
sale of a portion of the Company's bankruptcy claim against its customer,
Spansion Inc.

"Our business in the first quarter continued to be impacted by the
challenging global macroeconomic climate, coupled with weak capital
spending trends in the semiconductor industry," said Rhea Posedel, chairman
and chief executive officer of Aehr Test Systems.  "That said, net sales
of $1.3 million were up slightly on a sequential quarter basis and we are
encouraged by important new orders that we booked in recent months.  These
included a follow-on order of more than $1 million for our FOX-15 wafer-level
burn-in and test system along with orders from two customers for our new
Advanced Burn-in and Test System (ABTSTM).  The new ABTS family significantly
expands our product portfolio and provides us with an excellent opportunity
to grow our business going forward.

"Despite the near-term hurdles resulting from the current macroeconomic
cycle, recent reductions in our cost structure and improvements in our
product offerings have made me more confident in Aehr Test's ability to
increase market share and return to a growth path as industry conditions
improve to more typical levels," said Mr. Posedel.

At August 31, 2009, cash and cash equivalents were $2.7 million.  The proceeds
of approximately $3.3 million from the sale of a portion of the bankruptcy
claim were received in September 2009.  Aehr Test completed the first quarter
of fiscal 2010 with no outstanding debt and shareholders' equity of
$11.2 million, or $1.32 per share outstanding at August 31, 2009.

1 The Company largest customer, Spansion Inc. ("Spansion") filed for bankruptcy
  in February and March 2009.  The Company has filed a claim in the Spansion
  U.S. bankruptcy action.  In the first quarter of fiscal 2010, the Company
  sold a portion of its bankruptcy claim to a third party for net proceeds of
  approximately $3.3 million and recorded the amount in income from operations.

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).
