                 AEHR TEST SYSTEMS REPORTS FINANCIAL RESULTS
                        FOR FOURTH QUARTER FISCAL 2009

Fremont, CA (July 28, 2009) - Aehr Test Systems (Nasdaq: AEHR), a technology
leader in the semiconductor test and burn-in equipment industry, today
announced financial results for the fourth quarter and full fiscal year ended
May 31, 2009.

Net sales were $1.2 million in the fourth quarter of fiscal 2009, compared
with $10.9 million in the fourth quarter of fiscal 2008.  Aehr Test reported
a net loss of $4.0 million, or $0.48 per share, in the fourth quarter of
fiscal 2009, compared with net income of $6.5 million, or $0.74 per diluted
share, in the fourth quarter of fiscal 2008.  The net loss in the fourth
quarter of fiscal 2009 included non-cash charges of $1.3 million related
to restructuring and asset impairments and $338,000 related to stock
compensation expense.  Collectively, the non-cash charges accounted for
$0.19 per share in the fourth quarter of fiscal 2009.

 "Sales opportunities for our family of Advanced Burn-in and Test Systems
(ABTSTM) are gaining momentum, as we recently booked three orders, including
two from new customers and one follow-on system order from Integrated Service
Technology in Taiwan," said Rhea Posedel, chairman and chief executive
officer of Aehr Test Systems.  "We are selling aggressively to expand our
customer base for the ABTS systems in the coming quarters, which should help
drive top-line growth.  Our strategy during this downturn is to conserve
our cash and book additional production accounts with our new ABTS and FOX
products to grow market share.  We are optimistic we can achieve this goal,
as we have the strongest product portfolio in our company's history, with
our FOX wafer level test and burn-in systems, full wafer contactors and our
new ABTS products for packaged part burn-in and test."

Net sales were $21.4 million in fiscal 2009, compared with $39.0 million
in fiscal 2008.  Net loss for the year ended May 31, 2009 was $30.0 million,
or $3.55 per share, compared with net income of $10.6 million, or $1.24 per
diluted share, in the prior fiscal year.

At May 31, 2009, cash and cash equivalents were $4.4 million.  Aehr Test
closed the fourth quarter of fiscal 2009 with no outstanding debt and
shareholders' equity of $10.0 million, or $1.17 per share outstanding at
May 31, 2009.  As of May 31, 2009, the Company's backlog was $2.0 million,
compared with $18.6 million at May 31, 2008.

1 Related to accounts receivable of Spansion Inc., which filed for bankruptcy in
  Japan in February 2009 and in the U.S. in March 2009.
2 The three months ended May 31, 2009 includes a provision for excess/obsolete
  inventory of $1.5 million, $0.2 million severance costs, and a credit of $0.3
  million for settlement of cancellation charges accrued in the prior fiscal
  quarter. The year ended May 31, 2009 includes a provision for excess/obsolete
  inventory of $7.2 million, cancellation charges of $0.3 million, $0.3 million
  impairment of goodwill, and $0.4 million severance.
3 Excludes $4.9 million tax provision related to reinstatement of the valuation
  allowance.


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).
