                   AEHR TEST SYSTEMS REPORTS FOURTH QUARTER
                        AND FISCAL 2005 RESULTS

FREMONT, CA (JULY 19, 2005) - Aehr Test Systems (Nasdaq: AEHR), a leading
supplier of semiconductor test and burn-in equipment, today announced
financial results for the fourth quarter and fiscal year ended May 31, 2005.

Net sales were $3.3 million in the fourth quarter of fiscal 2005, compared
with $5.9 million in the fourth quarter of fiscal 2004.  The Company reported
a net loss of $1.7 million, or $0.23 per diluted share, in the fourth quarter
of fiscal 2005, compared with a net loss of $484,000, or $0.07 per diluted
share, in the same period of the prior year.

"As anticipated, net sales grew compared to the third quarter of fiscal 2005,
as we completed shipment of several MAX systems during the fourth quarter,"
said Rhea Posedel, chairman and chief executive officer of Aehr Test Systems.
"Current quote activity is the strongest we've seen in the last few years.
During the fourth quarter of last year and the first quarter of this year,
we've received orders for our MAX system from two new customers in Asia.
Additionally, a current customer, who is a leading wireless communications IC
manufacturer, placed a multi-system MAX order.  We have also received multi-
system, follow-on orders for our MTX-Fp+ products, valued at nearly $3
million," said Mr. Posedel.

"In June we announced the availability of the latest member of our FOX(TM)
family of products, the FOX-1 full wafer contact test and burn-in system.
After completion of the final milestone of the full wafer contact tester
development program, we expect to begin shipment of our FOX-1 systems in
calendar year 2005.  In addition to our development partner, a number of IC
manufacturers have shown interest in our FOX products, which parallel test an
entire wafer with a single touchdown and provide wafer level burn-in and
test.

"We are upbeat about the progress we've made as well as our future prospects.
However, we also recognize the need for bottom line improvement.  We believe
that, if we are able to execute on our goals of growing net sales while
controlling expenses, we should be able to markedly improve the Company's
financial results this fiscal year," said Mr. Posedel.

Fiscal 2005 net sales increased to $16.1 million, compared with $15.8 million
in fiscal 2004.  The Company's net loss in fiscal 2005 was $4.9 million, or
$0.66 per diluted share, compared with a net loss of $4.0 million, or $0.55
per diluted share, in fiscal 2004.

At May 31, 2005, cash, short-term investments and long-term investments were
$9.2 million, compared to $11.8 million at the end of fiscal 2004.  Aehr Test
ended the fourth quarter of fiscal 2005 with no outstanding debt and
shareholders' equity of $17.5 million, or $2.33 per diluted share. The
Company's order backlog, net of cancellations, at the end of fiscal 2005 was
$4.9 million.

"Given the levels of quote activity we're currently experiencing, we expect a
significant improvement in net sales in the first quarter of fiscal 2006,
when compared with net sales for the quarter just reported," said Gary
Larson, vice president and chief financial officer of Aehr Test Systems.
"Additionally, we expect full year fiscal 2006 net sales to increase
considerably over those of fiscal 2005."
